I am the same way... However, if I am talking for work, I can handle it just fine. Talking for work requires no emotion and it's straight facts. I recently had to represent my company at a hearing of sorts as the only speaker... And I did just fine. I always do. But put me in another situation and I'm socially inept and bordering on an anxiety attack.

Even in therapy, I have times where I get so worked up I can't speak. Yet, a hearing for work in front of many people and I am just fine.
