Honey, look. You're 20, right? 'bout the same age as me. I don't know what I want from life; I only know what I don't want. But that's a start, right? Process of elimination and all that jazz. I've decided not to worry about it too much because worrying about it gets me down and makes me cry because by society's standards I ain't worth anything. It's not an ASD thing, it's a young adult thing. The ASD part is just another obstacle on top of the quarter-life crisis.
But ASD isn't really a curse. Thinking of it like that will only make you miserable, because you're rejecting an inherent part of yourself. You gotta try to accept it and learn to work with and around it. Distancing yourself from the issue is only going to cause more problems. If you really want to overcome your ASD-related difficulties, you have to work on them, not ignore them. You'll have to identify the basic things that you have difficulty with first and start to understand how it ties into your ASD and why. Then you can start to improve those things.
Sorry I'm being vague but I can't be more helpful without knowing your specific circumstances and behavioural patterns. But if you ever do need advice or just a chat, I'm around. :)
