since the 7th grade

Since I had a *really* bad experience doing a book report in 7th grade I have never been the same since. I took F's on oral reports because I was too afraid to do them. I dropped out of college classes where oral reports were required and at almost every job I've had, I'm terrified when I'm called upon. My voice is shaky and I cannot control my facial expressions or think about what I am talking about. My new job requires everyone gives talks every so often on their work area to 20-30 people during lunch. I feel like quitting, but the worst part is the stress I go through every day thinking about it. It degrades the quality of my life and gives me stomach pain. I have been running from this my whole life and the handful of times I've faced the fear head-on, I've lost. I feel totally trapped.
