Suggest me a book that motivated the f**k out of you

So I really wanna turn my life around but the problem is that I have a lot of emotional baggage, and mental stress concerning my current life. This tends to get in the way of me trying to improve my life. I feel extreme remorse about a decision I made about my life, consequence of which is my current state of being. And being in this environment has made me mentally and physically ill. The mental stress has increased so much that I find it very hard to be productive. I will at some point start therapy but until I do that, I’d like to read something that’ll cheer me up and motivate me to go against all odds and achieve success. Real life stories would be great and please no self help books. I appreciate your suggestion, thank you!
