great pangs in stomach

I am 43 years old and get a pit in my stomach when I know I must speak in front of my collegues. I become tongue-tied, blush, and my voice wivers. Sometimes, I'm fine, sometimes, I'm at a loss for words.

I wish I could express myself to groups of people without having any pangs of anxiety. It's frustrating, and weighs on my mind days before I know I have to speak in front of a group.

I try to convince myself that it is only a few minutes of my life, and who gives a '$%*#' about them anyway! Wishing I could rid of myself of this anxiety that plagues me.
