In my limited knowledge of psychopathology I was suggest that you don't have autism- I'm sure the feelings you suggest are not symptoms of autism. Autism is an inability to empathise with others, am I right? What you seem to describe is mild paranoia, perhaps. Have you actually been diagnosed as autistic? It sounds more like schizophrenia to me, at a very mild level.
As for helpful advice about mental dissorders, I have two contributions. One is that many would argue that you are always in control of your mind. Whether you choose to exercise this control is up to you. Perhaps, if you want real psychological theory to back this idea up, you could take a cognitive approach to your disorder, say that "My thought processes telling me that I am under constant heavy judgement from those rround me is faulty. I am not under judement, there is no reason to be intimidated." Try a bit of auto suggestion.
The second is that if you do infact have a disorder and it is beyond your ability to control it, try to use it to your own gain. This may sound totally bizzare and perhaps a bit insulting, but pick up a copy of "Think and Grow Rich" by Napoleon Hill. Read the story about his deaf son. I have only just read it but I feel it would be most appilicable to you.
Oh yeah, and if I've totally overlooked the severity of your condition and the doctors start giving you pills, take the damn things!
Let me know if I'm looking at this totally the wrong way, but I think a guy can get over anything. Be that damn guy,
