Stage fright

If there is one thing that I hate more than studying is to have to speak in front of a group of people. Yeah that's right I suffer from stage fright. I've had this problem for as long as I can remember. I have an assigment on a book that I have to talk about in front of two classes. 

When the moment comes and i have to go up there and start talking I get the typical symptoms. Heart starts pounding hard, cheeks turn red, hands start shaking & voice goes high pich. I hate to have this problem because my mind understands that it's nothing to be afraid of. My mind gets it but my body doesen't & that's when i get mad at myself for not getting over this problem. Every time it's an issue & I'm sick of it.
