I don't mean this as a joke, but I think alcohol has been much used in an attempt to "self-medicate" for this problem. When I became old enough to try that remedy, I did and I thought for awhile that it took away the self-consciousness. Still, the basic trait of feeling in fear of mishandling social encounters remained unshaken. So, I didn't become a big drinker. I was ordered a med that was supposed to help - I think it was propranolol, a beta blocker. It didn't help me. Valium was ordered once, too. It didn't help, either. So, I've given up on medication as a help.
