At age 18 Alysia Sawchyn was diagnosed with bipolar I. Seven years later she learned she had been misdiagnosed. A Fish Growing Lungs takes the form of linked essays that reflect on Sawchyn's diagnosis and its unraveling, the process of withdrawal and recovery, and the search for identity as she emerges from a difficult past into a cautiously hopeful present. Sawchyn captures the precariousness of life under the watchful eye of doctors, friends, and family, in which saying or doing the wrong thing could lead to involuntary confinement. This scrutiny is compounded by the stigmas of mental illness and the societal expectations placed on the bodies of women and women of color. And yet, amid juggling medications, doubting her diagnosis, and struggling with addiction and cutting, there is also joy, friendship, love, and Slayer concerts. Funny, intelligent, and unflinchingly honest, Sawchyn explores how we can come to know ourselves when our bodies betray us. Drawing from life experience, literature, music, medical journals, films, and recovery communities, each essay illuminates the richness of self-knowledge that comes from the act of writing itself.
