I know how you feel. I'm much younger than you are but I have worked and found out that I can't do it. I cannot work at these fast food places and other odd jobs. It isn't just my AS either, I still have problems with anxiety and depression as well. I'm in therapy right now to get over that but the way I am now, I can never work anywhere without a degree of some kind, which takes a while to get.
Quite honestly, I can't give you any advice but maybe knowing that you're not alone in this will help at least a little. All I can say is don't give up hope, there is something out there for everyone to do.
