Good job with the studies, keep up the hard work! This with presenting however seems to be a big deal given the stakes and how bad it makes you feel. I have always sucked at it myself but since I lowered my ambitions during school years it never carried the same weight, like whatever happens happens. But this is not the right way I'm afraid, because in almost every professional line of work you have to present information to others and you can't have panic attacks about it. My first advice is more of a quick fix to get you going. Record your presentations in advance and then play them during class. In this time and age there should be a way to show a video in any classroom. This way you can still take questions, fill in the gaps and provide additional material without having to do all the talking. Naturally discuss this with the professor first and please don't be ashamed to tell them how difficult it is for you to present. And if he's being a dick about it, take it higher up. You have a condition that inflicts you real damage so this should (in a perfect world) trump any cultural attitudes. The best long term solution however is to practice and work on your public speaking skills, no matter how painful it might be in the beginning, because this will be more important for your career than any grades or courses. Maybe you can combine this with the recording technique and gradually increase the amount of talking on the spot. Record some parts, live present others. And if you're creative with it this become a style of your own, probably even more interesting and engaging than just plain (boring) talking everyone else does. This is just me dreaming, but I'm getting back on my Masters in Aerospace next week and there are definitely some scary presentations waiting for me too :)
