I recently read a book on bipolar called "Welcome to the Jungle" by Hilary Smith... it was funny, irreverent, and taught me a lot of stuff I didn't understand about bipolar disorder. Having been recently diagnosed, it was comforting to find a book that didn't treat the diagnosis like a death sentence - it made it ten times less scary, while at the same time providing relevant information. I'd recommend it for any young adult struggling to come to terms with their diagnosis- it'll actually make you laugh!
