I wish I could say the terror would go away if you took a class, but people who take my public speaking class agree with what I tell them in the first week: you're still going to be scared, but you're going to be able to hide it and distract us from that a LOT better.

(Mind you, they're speaking in their second or third language, which is nerve-wracking enough one-on-one, but can be paralyzing with an audience in the room.)

However, I can also attest to the fact that it mostly does get better with practice. I used to be terrified of leading classes as a teacher, but years later, I can't even really remember how that felt.
