Self-harm is causing pain or harm to yourself on purpose. It is not the same as a suicide attempt.


Self-harm is a sign of distress and problems with coping skills. People may self-harm when they feel intense anger or frustration. Some say it feels like tension release. Others may do it for a sense of control or to feel something other than numb.
