About self-harm 

We all experience difficult feelings at some point in our lives, and cope in different ways.

Some of us might use self-harm to try to cope, or think about doing this. Or you might have heard about self-harm but aren't sure what it means.

Self-harm can affect us in lots of different ways. It can feel hard to understand or talk about self-harm, but we're here to help.

If you feel overwhelmed, or like you want to hurt yourself or someone else, you can:

If you feel like you may try to attempt suicide, or you or someone else is seriously hurt, this is an emergency. You should:

  • Call 999 and ask for an ambulance
  • Tell an adult you trust and ask them to call 999 for help

Tips for coping with self-harm

We have tips and ideas on how to cope with self-harm right now or where to get support.

If you're trying to support another young person with self-harm, we have tips and advice.

What is self-harm? 

Self-harm is when we hurt ourselves to cope with difficult feelings.   

We might self-harm for many different reasons, and in different ways. Sometimes we might not realise we've self-harmed until afterwards.

Lots of people don't understand self-harm. Because of this, they might do or say things about it that are hurtful. This is called stigma

Let's break down some myths that can lead to stigma.

Self-harm can take many different forms, like:

  • Cutting, biting, hitting or burning ourselves
  • Hitting things, like punching a wall
  • Poisoning ourselves, like taking overdoses
  • Doing things that are bad for our health, like drinking too much alcohol or having unsafe sex
  • Not taking care of ourselves, like not eating or washing
  • Digital self-harm

We might hurt ourselves in other ways too. Or we may hurt ourselves and not think of it as self-harm.

Knowing more about what self-harm can look like can help us know when we need help and support.

Self-harm can come in different forms. I didn't know I was self-harming during the biggest part of it.

We might hurt ourselves in non-physical ways. Like hurting our feelings or thinking badly about ourselves. Non-physical self-harm might not be recognised or understood in the same way as physical self-harm behaviours.

Non-physical self-harm might include things like being self-critical, insulting ourselves or digital self-harm.

Digital self-harm

Digital self-harm is where we use social media and the internet to hurt ourselves. This can include: 

  • Sending hateful or abusive messages to ourselves, or about ourselves, online 
  • Looking for or spending a lot of time in conflicts online 
  • Searching for information that is harmful or discriminates against us or people like us
  • Engaging with or creating online content that promotes self-harm

Lots of people might think that only girls self-harm. Doctors or services for self-harm might see girls more often, but that doesn't mean they're the only ones who need support.

Anyone can self-harm, no matter what their gender is. And myths like this might make it harder for us to seek help. Especially if we don’t feel like we can get help, or we think people will judge or misunderstand us. 

Anyone can self-harm at any age.

But it may be harder to know what self-harm means when we're younger. We might not think of what we're doing as self-harming. Or not have the words to ask for help.

Some of us might hide that we self-harm, and some of us might not. Our self-harm might not be visible. Or we might not even know we’re self-harming.
 
But self-harm can bring attention to the fact that we need support or reassurance. 

Someone might call self-harm attention-seeking because they don't understand. Or they may focus on what we're doing, rather than the reasons behind it.

The myth that self-harm is attention-seeking can make shame and stigma worse. This can make it harder for us to ask for the help we need. But there are lots of different support options for self-harm that might help. 

Sometimes we might try different ways to keep ourselves safe and to prevent self-harm. These are also not attention-seeking. 

Remember: you deserve help and support.

Some people might think that we self-harm because we're copying people we know who self-harm. But there are lots of reasons why we might self-harm. And just being close to someone who's self-harmed doesn't mean we'll self-harm too.

But we might:

  • Start to see self-harm as a ‘normal’ response or way to deal with difficult feelings or experiences.
  • Learn ways to harm ourselves from someone else.
  • Find friends that also self-harm or struggle with their mental health. This might be because of a shared understanding. Or because we worry about others judging us. 

For whatever reasons we self-harm, finding the right support is really important. We also have tips to support another young person who self-harms. 

Some of us self-harm once and then never do it again. Or we may hurt ourselves over a long period of time. No matter how long we self-harm for, it isn’t just a phase. And it's important not to ignore it.

Being told it's ‘just a phase’ or to ‘stop it’ won't help stop self-harm. It might make some of us feel worse. This could lead to us hurting ourselves more.

We all need to feel understood. And with the right support we can learn new ways to cope with our feelings.

If we self-harm, it doesn't always mean we're thinking about ending our life. 

Sometimes we use self-harm to cope with difficult feelings and experiences. It might feel like only thing that can help us at the time. But there are other things that can help, which you can find in our tips for coping with self-harm

Some of us who self-harm might also experience suicidal feelings. But it doesn't always mean we want to die.

If you have seriously hurt yourself or feel like you might attempt suicide, this is an emergency. Call 999 straight away to make sure you get help.

Social media and online forums do not always cause self-harm. They can provide helpful sources of support to manage self-harm, like:

  • Sharing distraction and coping methods
  • Sharing things that have gone well
  • Talking to other young people who understand
  • Getting support from other organisations

It's important to find safe and trusted information about self-harm. You can use websites like Mind, Alumina or Childline.

But social media can also bring up difficult feelings. Some people might:

  • Share images of self-harm 
  • Post detailed descriptions of self-harm
  • Encourage others to self-harm through comparing or ‘competitions’
  • Bully others online

We might also engage in digital self-harm.

If you come across triggering content like this, you can block and hide things from your feed.  

You can report anyone you're worried about, or who seems to be trying to make others feel worse. You can find self-harm reporting guidelines that might help on the Internet Matters website.

Don't fall down a rabbit hole of searching for self-harm on social media, it does more harm than good.

We might not even know we're self-harming. Or we might self-harm in ways that others can't see, or that doesn't leave scars or injuries. Or we might hide self-harm.

We might hide it because we feel ashamed or worried about how others will react. Or because we don't want to feel like a burden.

We might also not recognise our self-harm. It can look like other things, like behaviours we might show when we're angry. So it may take longer for someone else to notice, or for us to get help.

Self-harm can look different for all of us. Sometimes we might compare ourselves to others and feel like our situation isn't serious enough to ask for support.

We don't need to feel ashamed of self-harm. Talking about things can help.

Self-harm might relate to different types of mental health problems. But if we self-harm, it doesn't always mean we have a mental health problem like depression.

Whether you have a mental health problem or not, you can still get support for self-harm.

Remember: mental health is about how we think, feel and act. Looking after our mental health is important, whether we have a mental health problem or not.

With the right help and support, we can reduce self-harm and then stop self-harming.

But it might not always be easy. Recovering from self-harm is a process which can look different for all of us.

For some of us, recovery might be about managing the urge to self-harm or finding new ways to cope. For others, it might be about finding safe places to talk about how we're feeling. Recovery is not always about reducing or stopping self-harm completely.

Sometimes we might come across challenges in the process, and that's okay. This is about learning what does and doesn't help us.

Why might I self-harm?

We might self-harm for many different reasons.

We might use self-harm to deal with something difficult in our lives. Or as a way to cope with overwhelming feelings. Sometimes, we might not know why we hurt ourselves.

Some of us might self-harm once and then try other ways of coping. But some of us might feel that it helps, so we start to rely on it.

Some reasons why we might self-harm include:

  • Living with physical or mental health problems, or experiences linked with poor mental health, like anger or hearing voices.
  • Feeling lonely or isolated, like if we move to a new area, or have no friends. 
  • Stressful or upsetting experiences, like problems with relationships, housing, school, college, work or money.
  • Bullying, like being bullied, bullying someone else, or both. 
  • Experiencing abuse or discriminationlike against our sexuality, race or gender identity.  
  • Intrusive thoughts, which are distressing thoughts that keep coming into our minds when we don't want them to. 
  • Struggling with how we feel about ourselves, like low self-esteem or body image worries.
  • Feeling uncertain about our identity, like about our gender, sexuality, race or religion.
  • Feeling misunderstood, like not knowing how we feel, or being unable to tell others how we feel. 
  • Experiencing sleep problems, which can affect our wellbeing
  • Not feeling accepted for who we are or supported by the people around us.
  • Using alcohol or drugs, which some of us might use to try and cope. But this might only help in the short term and could make things harder for us in the long term. We might use self-harm at the same time as drugs or alcohol.  
  • Feeling unsure how else to cope or show we need support, like if other people around us are self-harming, we might see this as a way to cope. Or we might feel like we need to self-harm to show what we're going through.
  • Being impulsive, which is when we act without thinking about what might happen.

Some of us might find it harder to cope with these experiences, or struggle more with recognising how we feel. This might be because we're neurodivergent, like being autistic or having ADHD. Or because we've experienced trauma. But there might be other reasons too.

Growing up as an undiagnosed autistic girl, self-harm was my crutch to lean on. It was my piece of control in a world that I didn't understand – Rose, 16

After my mother passed away, I went into a really dark place and I didn't think there was any way out unless I self-harmed – Reggie, 15

Some young people we spoke to said they self-harmed because they were trying to:

  • Show how they feel without speaking
  • Distract themselves from how they were feeling 
  • Cope with, or escape from, painful feelings, thoughts or memories
  • Feel more in control
  • Punish themselves for something
  • Stop feeling disconnected from themselves or the world
  • Create a reason to look after themselves, like caring for wounds
  • Manage thoughts of suicide – for more information about suicidal feelings, visit the YoungMinds website

What are triggers? 

Some thoughts, feelings and experiences may cause urges for us to self-harm again. These are called triggers.

We all have different triggers. But understanding our triggers or the reasons why we self-harm can help us to find ways to stay safe. A safety plan can be a helpful place to write these down.

The reason was usually due to feeling stressed and wanting to let it out. However, this was short-term, and because I wasn't dealing with the root cause of the stress, it came back, so I felt like I was stuck in a cycle – Carys, 18

If you don't understand why you're self-harming, that's okay. You're not alone and you can still get help.

Self-harm and discrimination 

Discrimination can have a huge impact on our mental health and the support we get. If we experience discrimination, this might also make us more likely to self-harm.

We might not feel like it's safe to talk openly about how we feel. Especially if it relates to parts of our identity, like race, religion, culture, gender or sexuality.

And we might not always get the support we need from the people around us, or healthcare professionals. We might find that people don't believe or understand us. Or feel that support isn't inclusive or suited to our needs. It can make it harder to engage with available support.

We might worry about being judged or treated differently. We might have faced stigma when asking for help, or know people like us who have experienced this. This means we might only ask for help when things feel really bad. Or we might not ask for help at all.

Discrimination is never okay – it's not something that any of us should have to put up with. You deserve support.

If you've experienced discrimination, either online or face-to-face, you can: 

Discrimination and unfair treatment can lower our self-esteem – it's important to find ways to look after ourselves.

How do I tell someone I've self-harmed?

Self-harm can bring up difficult emotions, like guilt or shame. And this can make it hard for us to ask for help.

Try to tell someone you trust as soon as you feel ready to share. This could be someone you know like a parent, carer, guardian, friend or partner. Or professionals like a teacher, doctor, social worker or counsellor

If you don't have a safe place to turn to, or don't have someone you trust, you can find organisations and services that can support you on our useful contacts page.
 
Or you can connect online with other young people who might have similar experiences, on forums like The Mix or Childline.

Remember: you don't have to go through this alone. 

Once I realised that I was self-harming, I found it really hard to find help. I didn't know who to talk to, or how to put into words everything I was feeling – it was just too big – Cal, 14

Before telling someone you've self-harmed

Before you talk to someone, you could:

  • Write down how you feel. You could do this when you're feeling calm, or just before or after you've self-harmed.
  • Practise what you want to say. Think about what you're comfortable sharing. You can also speak confidentially to Childline or The Mix first.
  • Think about supportive people who you might want to talk to. If you don't feel like you have anyone to open up to, you can find trusted organisations and services on our useful contacts page.
  • Think about how you want to tell them. You could talk face-to-face, write a letter, or talk over phone or text. You could also tell them while you're doing something together.
  • Plan to do something kind for yourself after. Telling someone isn't easy and we might feel scared, stressed or anxious. But it's something to be proud of.

Low self-esteem can make us feel like we're a burden to others. This isn't true. But it can make it feel harder to ask for help. If you feel like this, you could try our tips for building confidence and self-esteem

More information on talking to others

Our information about opening up has more tips and ideas for how to talk to other people. We also have information on how to talk to your doctor.

Starting the conversation 

If you feel ready to talk, you could think about how to start the conversation. There's no right or wrong way to do this. But here are some things you could say:

  • ‘This is difficult for me to talk about, but I need to tell you something.’
  • ‘I need your support with something, can we talk?’
  • ‘I wanted to tell you that I've been self-harming because I feel…’

Talking about self-harm

When talking about self-harm, you could:

  • Ask someone you trust to help you explain or to tell someone for you, if they feel able to.
  • Explain what you'd like from them. Do you want them to listen or to help you find support?
  • Only share what you're comfortable with. You can tell them as much as you feel able to.
  • Take a pause if you need to. Remember that you can come back to the conversation at another time if it feels safe to do so.
  • Talk about confidentiality. If they're worried about your safety or someone else's, then they'll need to tell someone. You can ask them to let you know if they need to do this.

Eventually, I told my parents, who immediately supported me and helped me seek out counselling, in which I voiced my reasons for self-harming, and the feelings behind it – Carys, 18

What if they don't understand?

We know that people don't always understand or react in the way we need them to. They might not want to understand self-harm, or be able to right now. Or they might feel too upset or shocked. 

Remember: it's not your fault, and there will be someone who can support you.

If you experience this, try not to give up or take it personally. They might need more time. Here are some tips:

  • Be honest about why you're telling them and let them know that you trust them to support you.
  • Try and understand how they might feel, like feeling frustrated, overwhelmed or confused. You could try and talk to them again another time. Or you could try talking to someone else instead.
  • Share information to help them understand. Sometimes people react in unhelpful ways because they don't understand or know how to help. Sharing information, like this page, might help them understand what you're going through.
  • Try a different way of talking to them – could you write a letter or draw how you feel? Can you think of someone else you trust who can help you speak to them?

Sometimes people's responses can be unhelpful. But you should feel proud that you reached out for support.

Some people might not understand – it's their opinion, not the truth. If that happens, it's not your fault, they're not right.

Self-harm injuries and scars 

Not everyone who self-harms will have scars, because self-harm can look different for all of us. But some of us will have scars.

If we have self-harm scars, they might fade. And we might feel a mixture of things about this.

We might compare ourselves to others and the scars and injuries they might have. This can be triggering, or might make us feel like our experiences don't matter.

But it's important to remember we're all different, and we all deserve help and support.

We have more information about coping with scars.

Self-harm injuries

If you're worried about an injury or your health, talk to your doctor or ask a trusted adult to help you get medical support. 

If you can't see a doctor or nurse right away, call NHS 111 or call 999 if it's an emergency.

It's important to look after self-harm injuries so you don't get unwell from them. For more information, visit the Self Injury Support website.

If you feel like there are other people suffering more than you, that doesn't make your pain less important, or less painful to you – Leigh, 18

What is a relapse?

When we have gone for some time without self-harming, but then started again, we might hear this called a ‘relapse’.

Relapse is nothing to be ashamed of. We can all find ways to cope again. 

We might relapse because we're:

  • Feeling a really strong emotion, like sadness, stress or anger
  • Going through a difficult situation, like exam stress or problems in our relationships
  • Experiencing trauma, which means a response to something stressful, frightening or distressing that's happened to us
  • Feeling hurt or unwell

We might relapse for other reasons. Or we might not know why we've relapsed. And that's okay. We also have tips to help you cope with relapse.
