"Even more than the depression, it was my anxiety and agitation that became the defining symptoms of my illness. Like epileptic seizures, a series of frenzied anxiety attacks would descend upon me without warning. My body was possessed by a chaotic, demonic force which led to my shaking, pacing and violently hitting myself across the chest or in the head. This self-flagellation seemed to provide a physical outlet for my invisible torment, as if I were letting steam out of a pressure cooker."
