Do you get terrified to sing/perform/act in front on stage in front of a big audience? Can you do it at all? Or are you pretty comfortable with it?

I've sang a few times to an audience, solos for Chorus. I get nervous more before I perform than I am WHILE I'm doing it. I've just been invited to sing a full song at a recital in June. I was so nervous the last time I sang a solo for Chorus a few weeks ago because my bitch chorus teacher gave me the crap solo I didn't want at the last minute as a last resort, then tried to make me give it up because she hates me (I know she does. She's so mean to me and sabotages any attempt of me singing frequently) by telling me that I shouldn't singing because "I'd embarass myself." I'm kinda nervous, since I've never sang a full song to an audience before, but it's pretty exciting. Besides a senior in some high school, I'm the only older performer singing at the recital. It's pretty neat.
