Most days, Shalene Gupta was the person shed always aspired to be. She was hardworking, excelled at work, and had a long-term boyfriend who she desperately loved. Then, every month like clockwork, it all came crashing down in fits of rage and inconsolable sorrow. Work became meaningless, and she struggled to get through the day. The lows were subterranean. After years of struggling to get an answer from doctors, Shalene learned she was one of millions who live with premenstrual dysphoric disorder (PMDD), a severe form of PMS. The physical and mental effects of this disorder are undeniable, but for decades some doctors didnt even consider PMDD a real condition. How could so many people be suffering at the hands of a chronic condition that doesnt even exist? The Cycle uncovers a hidden epidemic, delivering the definitive portrait of a widespread chronic illness most people havent even heard of. From a historical overview of feminist debates, to on-the-ground interviews and a searing critique of menstrual stigma, Shalene Gupta lays out how disregard for this disorder has left too many people scrambling for appropriate healthcare. Deeply researched, movingly intimate, and refreshingly hopeful, this book is essential reading for any curious reader, especially those navigating a world ill-equipped to support their health.
