Marcus is demonstrating the symptoms of binge-eating disorder, as he regularly consumes large amounts of food during times of anxiety and experiences guilt afterward. However, he does not engage in compensatory behaviors like purging or excessive exercise, which are characteristic of bulimia nervosa. Anorexia nervosa involves a severe restriction of food intake and often involves distorted body image and intense fear of gaining weight. Dissociative identity disorder, also known as multiple personality disorder, involves a disruption of identity characterized by the presence of two or more distinct personality states.
