I have a huge fear of public speaking and i have a speech to do!!?

since its speech u'll prolly have to make the speech, but you can try talking to ure professor about another way out of it. If you can't just pretend your reading to kids or they're all sleeping, pay attention to other things, remember....they're all humans just like you and you'll be the audience for them also....so they go through the same as you. Its better just realizing that theres nothing to be scared about
