Im having the same sort of stress-episodes at the moment. I just did my first year uni exams at the start of may, and we get a list of people who have passed all of them on 5th June. I feel like I should start revising again for my inevitable resit for anatomy and physiology exam, which is silly cos despite the fact I almost know that i failed it, it would be a total waste of time if I've passed, and resits arent till august so if I have failed I'll have a good while to prepare for it after results come out.
Just relax, watch tv or something to take your mind off it, then go to sleep. I'd say there's no point in trying to sleep with it still running through your head. Been the
re, tried that, failed miserably.
