It can often help to find support and understanding by talking to someone, such as a friend, family member, doctor or counsellor. This can be a general source of support for a person who has self harmed, and can also help them to explore their feelings and to gain an understanding about their problems.
Self harm is quite different to a suicide attempt. A suicide attempt is a deliberate attempt by a person to end their own life. Often suicide attempts are unsuccessful for various reasons. Whilst the person may feel disappointed that they are still alive, this gives doctors and nurses an opportunity to intervene, and to find out what help and support may be needed. Suicide attempts are often an indicator of serious but treatable mental health problems, which require prompt and specialist attention.
