I had that problem, in excess of "normal" (would forget my name if I had to stand up and talk).

I'd find a Toastmaster's group and see if you can make any headway in a few weeks (or calm yourself some that you are at least working on the problem?):

I had 20 years therapy and I can talk now without dying but I'm still anxious, I can recover though and make it through. I think you have too much focus on the fear/yourself and not enough "out there" and I found that hard to learn to adjust, give myself "space" between what I'm asked/the "problem" and my response. One has to learn to short circuit that initial panic and then things can "flow" naturally. With therapy that can take a long time but I've never had meds so I don't know if they'd help or hinder/slow your thinking down so even if you weren't panicked, you wouldn't be able to remember/think as well? I'd try them maybe, see if they help and join a public speaking group to see if that could help. The best remedy is practice and that takes lots of time too.
