Hey, you need to step away for a bit. First of all...how long have you been going at this? Maybe it's been too long at one time. I have ADD and I'm taking classes at the University on-line and it stresses the hell out of me at times, and I never did well in school before in my life but now I'm so determined, I've been getting all "A's". I just calm myself down in whatever way works for me...even if I have to shut out the world...it's that important. OR...if everything else is on your mind and you have to do something else and that's bugging you out, go do that first, then relax, eat, take that shower or bath, take your meds if you have to, settle into your area where you study, or take your exams, and get it done! Just do it....
