do you get nerves speaking in front of a huge crowd?

It depends. I am a Lector at my church so I read in front of large crowds on a regular basis. I am, however, READING something I DID NOT WRITE. But I do practice so that I read it well making it understood to the reader. I used to get very nervous, so nervous the altar servers could see my pant legs shake. LOL! I joined a writing group where we have to read aloud what we wrote. My first day there I was nervous as heck. Of course it was a small crowd but it WAS something I WROTE. What I have learned, there really is nothing to be nervous about. As for reading at church, everyone makes mistakes, no one is perfect and what are they going to do? Fire me? And reading my own work out loud helps me to hear what I have written.

i do all the time. . .if there's more than 2 or 3 people i get lightheaded, dizzy, and nauseous (even if it's family)
