public speaking course

I have a course in public speaking at the university. And I am very nervous because I am suffering from severe anxiety! help!?
Is there a pill that can be prescribed for a day that will alleviate my anxiety? (and my doctor prescribed me Zoloft havent taken yet, but because I want to see how long I can go without.) Has taken medication and was able to get up front, with the number without problems? So thank you very much, but I'm looking for some Personal experience!
I know that my sister started taking Celexa I think it is called and that helped a little anxiety. There are, however, will be a delight wonderpill means that in total more than anxiety, work is placed opposite feelings and calming.
