mrflowers: I can completely understand your fear/ anxiety. Even after years of cognitive therapy, I still find myself getting this reflexive fear every time I have to do something new and - particularly- in public.
However- there is a tried and true method to disassemble your fear: write out on paper (or here (even better IMHO)) the WORST case scenario that you think that may transpire this semester at culinary school. Write it out in some detail- not only "I'm going to fail", but try to get specific about some of the things you're afraid of, that generate anxiety. Remember- this is the worst case scenario. I guarantee- when you look at your words on paper/screen- you'll realize that most of those things are NOT going to happen. I do this when I'm feeling anxious, and once I see my fears staring at me in letters....they lose some of their power. My rational mind can now look at them. Physiologically- my forebrain is examining them instead of my primitive brain.
Another thing. You are projecting your present thoughts into a future situation. You're expectations are pure fantasy. I've never once walked into a situation that worked out EXACTLY like I thought it would. Never. There was also little annoying shit I had to deal with, as well as nuggets of unexpected gold.
SO: if you're going to be projecting a fantasy into the future- have you considered turning your fantasy around a little bit? Right now you're probably seeing all the bad things that COULD happen. But what about the GOOD things that could happen? What if you make an unexpected friend? What if you expose a talent that, until now, has been hidden from you? What if this serves as a springboard to a cool career? All those things are possible too, right?
