In 1995, Hadley Freeman wrote in her diary: "I just spent three years of my life in mental hospitals. So why am I crazier than I was before????" From the ages of fourteen to seventeen, Freeman lived in psychiatric wards after developing anorexia nervosa. Her doctors informed her that her body was cannibalizing her muscles and heart for nutrition, but they could tell her little why she had it, what it felt like, what recovery looked like. For the next twenty years, Freeman lived as a "functioning anorexic," grappling with new forms of self-destructive behavior as the anorexia mutated and persisted. Anorexia is one of the most widely discussed but least understood mental illnesses. In a brilliant narrative that combines personal experience with deep reporting, Freeman delivers an incisive and bracing work that details her experiences with anorexia--the shame, fear, loneliness and rage--and how she overcame it. She interviews doctors to learn how treatment for the illness has changed since she was hospitalized and what new discoveries have been made about the illness, including its connection to autism, OCD, and metabolic rate. She learns why the illness always begins during adolescence and how this reveals the difficulties for girls to come of age. Freeman tracks down the women with whom she was hospitalized and reports on how their recovery has progressed over decades. Good Girls is an honest and hopeful story of resilience that offers a message to the nearly 30 million Americans who suffer from eating disorders: life can be enjoyed, rather than merely endured.
