The case we describe is Arianna (a 13 years old female student). She is daughter of separated parents, and lives with her mother. After the removal of the father, she started to have weight problems, with a ponderal increase of 11 kg, associated to a mood decrease. In this manuscript we describe the steps of psychotherapy suitable in a girl suffering from both eating disorder and major depressive disorder. Therapy aims were: 1. help the patient to change the relationship with her eating disorder; 2. help to develop a meta cognitive selfawareness; 3. reduce the depressive symptomatology. As consequence of the achieving of therapy objectives, patient would develop an useful mindset to globally redefine the way she looks herself and the world around.
