I've always found manic depression fascinating. I recommend the book "Electroboy: A Memoir of Mania" by Andy Behrman. He talks primarily about his manic phases, how he would rush out and buy things he couldn't afford, get into weird sex situations, fly round the world for no reason, and so forth, and how he eventually wound up involved in art forgery, before getting caught and deciding to submit to electroshock therapy. This Sebastien Marshall guy really sounds exactly like him.
