How to fix my self-esteem (Asperger's)?

I'm very sorry that you feel this way and are having this difficulty. I really am probably not qualified to be much help but maybe talking to your uncle or someone else about how you feel would help. I also know that sometimes you have to find new interests which can be hard to go through but I think you'll find that you can do well in them and that will help. You shouldn't worry about comparing yourself to other people it may be frustrating having aspergers but in some ways it gives you the opportunity to be achieve great things with what you are passionate about. Anyways the one thing I wanted to say was I would recommend this book called "The Big Short" I read recently. One of the main guys discussed in it is a hedge fund manager with aspergers and I found it truly inspiring and it may be really neat to read about someone who could figure something out that no one else could.
