Self-injury: What is it?
While self-injury may bring a momentary sense of calm and a release of tension, it's usually followed by guilt and shame and the return of painful emotions. And with self-injury comes the possibility of more serious and even fatal self-aggressive actions.
Because self-injury is often done impulsively, it can be considered an impulse-control behavior problem. Self-injury may be linked to a variety of mental disorders, such as depression, eating disorders and borderline personality disorder.
