Scenаriо: A 13 yeаr-оld student is stаrting her freshman year at "A. High Schоol" with classmates she has known since kindergarten. She is 5 foot 5 and weighs 120 pounds. She has a history of excelling in all subjects and sports. Upon her first day, she was ridiculed by her classmates for being "fat" and was not invited to sit with her friends, at the table during lunch. As a result she quickly developed unrealistically high self-expectations in attempt to "fit it." Three months have passed and she has avoided all social situations. She is no longer participating in school sports, however she is exercising 5 hours a day. She reports that she is excessively preoccupied about her weight and desire for social acceptance. She continues to state that "I try to calm my thoughts by working out 5 hours a day." She has not menstruated in 3 months, due to excessive weight loss. What diagnostic criteria does the student meet?
