This is Nicole Richie, who was a very beautiful model until she turned anorexic. She is now dancing with death. In anorexia the patient starves herself to death under the delusion that she is fat. This is an affective disorder that is a form of obessive-compulsive disorder. In bulimia, another eating disorder, the patient can eat themselves to death.
In my opinion she needs a stint in a mental hospital. This is for her own good. Psychotherapy is used as a treatment.
