Talking about books that hit you hard and make you feel depressed, look no further than The Book of Despair, by Fernando Pessoa.
No other book that I know of goes even closer to that one, at least for me. It it greatly written, but I couldn't finish it, because it wasnt good for my mental health at the time.
EDIT: I've seen that they translated it into English as The Book of Disquiet.
