Marya Hornbacher wrote her first memoir, Wasted, when she was 23 years old. Within a year of its publication, she was diagnosed with a rapid-cycling form of bipolar disorder. (See Chapter 5 for a discussion of bipolar disorder.) Hornbacher spent the next 10 years struggling with alcoholism and bipolar disorder; her struggles are recounted in her subsequent memoir, Madness: A Bipolar Life (2008). Although the flagrant symptoms of eating disorders were mostly behind her at the close of Wasted, in her later memoir, she reported occasional periods of restricting or purging as she struggled with manic episodes. She recounts that these periods of disordered eating were attempts to regulate her extreme moods. Her experiences highlight the frequent comorbidity among people with eating disorders.
