Hmmm, I have been there...so maybe this will help. I always feel anxious when I have to get up in front of people for any reason...a speech, singing, acting, etc. and usually geta queasy stomach. But, once I do get on that stage or in front of the audience, I forget all about my nervousness and get totally involved in what I need to do. That always settles my stomach, because I am no longer thinking about the fear. Maybe that will work for you as well.
It\'s all right to have butterflies in your stomach. Just get them to fly in formation.
