Suggest me any book that can improve an extemely low existent self esteem

Hi everyone,

My experience from childhood and school live has made me understand that I am no better than worthless trash. To solve this problem alone I must do something to rebuild my sense of self worth and identity, thus throughout the years I have pushed myself to the extreme to consume knowledge, that is , I have made myself to believe that my self value is solely dependent on the process of reading and thinking. Without that process, I will fall back to the realization that I am a piece of total, absolute, lowest trash. But until recently, my therapist helped me to realize the fact that even though I have already read a lot, I have never gained any self value from it, I have made myself a pillar of knowledge, but it is never built on a solid base… I am not sure what to do now, I am not able to see options other than relying on knowledge to save myself, but this seems not to be the way… Anyway I think I need the help from you guys, if you are so kind, may I ask what books(it can be any type of book) have pulled you from the hell of an almost non existent self esteem? 

This is my first time posting on reddit, let me know if I have violated the rules or something like that, I will delete the post immediately. 
Much appreciated.
