Well, I'm in school also and there has been a lot of stress for me too. I guess I'll just throw out all the things that have worked for me. Meditation, working out, studying more so that I am just not worried, meeting with the counselor, meeting with teachers when I have questions, getting a tutor. Well, those are the ones that I can think of right off hand. I don't have the sleeping problem like you do. Basically when my head hits the pillow I'm out. I guess maybe something else I could suggest would be to ask your doc about sleeping meds. I know that the idea probably sounds terrible, but maybe if you just took them for a week or so you could show your body and brain that sleep is actually beneficial to reducing stress levels. Maybe then you could get sleep. Also, before you take any herbal supplements make sure you talk a doctor also. If you are on any medications now there could be drug interactions that would make the whole stress-circle worse. I feel for you, though.
