Article summary

Self-harm is when a young person hurts their own body, often by cutting, scratching, hitting, burning or swallowing something harmful, to cope with emotional pain that has grown too big to put into words. It’s frightening to discover, but for many young people it's a way of surviving difficult feelings, although some also have thoughts of ending their life, and every young person's reasons are different. With understanding and the right support, things can get better.

Key takeaways

  • Self-harm is often a way of coping with overwhelming feelings. Some young people who self-harm also have thoughts of suicide, and reasons differ.
  • It is more common than most parents realise, especially in the teenage years, and every episode deserves a calm, serious response.
  • Self-harm often grows from pain a young person cannot yet put into words.
  • Old advice like ice cubes or pinging an elastic band can backfire. What tends to help is understanding what the self-harm is for.
  • With the right counsellor and steady support at home, many young people find safer ways to cope and move through it, though progress varies.
