You honestly want to conquer your fears? Ok then, last year I did my first presentation in over 10 years, and beforehand, the thought of doing any public speaking would make me want to vomit. Now I've done 3 presentations in total last year, and all because I pushed myself to practice.
The best thing you can do at this stage is get someone you trust and feel comfy with to practice in front of, and yeah, this in itself will be difficult. I didn't have anyone to practice with, but I accidently found out that I wasn't so nervous giving presentations to children so ...well, thats another story. If your uni has any opportunities to volunteer with kids, try it, you may end up gaining some confidence from speaking to them one-to-one, then eventually you may get confident enough to say hello to the entire class, etc etc
Anyway, even small practice presentations will make you nervous. Just get the idea into your head that you will get anxious (so it doesn't suprise you after trying to supress it) and keep practicing. In front of a mirror is good too, and don't expect to be great from the start.
What sort of presentations are you hoping to do Nick? What subject?
