This painting represent self-mutilation disorder, also referred to as self-harming, self-injury, self-inflicted violence or cutting. It’s typically not meant as a suicide attempt. Rather, self-injury is an unhealthy way to cope with emotional pain, intense anger and frustration. 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. Self-injury may be linked to a variety of mental disorders, such as depression, eating disorders and borderline personality disorder.
