When I was a kid I had a wonderful teacher who took me through giving presentations gradually. She started me out with just 1 person for the first presentation, then a few for the next one, then a few more. By the end of the year I was speaking in front of the whole class. Now I can speak in front of a bunch of people without much worry (except for the usual jitters that everyone gets). I'm so glad you went through with it, you should be proud!
