What book will help me get out of a dark place in life?

I'm currently suffering with Anhedonia, apathy, numbness, and extreme social and emotional avoidance. What book should I read to change my outlook, as I direly need it. It could be anything. Just to make me understand that my perception of life and the world itself is not true and there is more to it. Could be any type of book, except psycho analytics books. I read Psycho-Cybernetics and it didn't stick with me at all. I hate the books that give a million tips and a hundred steps, too overwhelming. And I don't like overly optimistic tones. Just something simple, like The Alchemist or Into The Wild or less classic books that could help me.
