I'm up at 3:30 in the morning and I have to get ready for school in two and a half hours.  I tried everything, but NOTHING seems to be working.  I tried xaxax and while it did make me dizzy temporarily, it didn't knock me out.  I need sleep because I realize that it's at the root of much of my anxiety, yet it seems like when I need it, sleep doesn't come to me naturally.

I know part of the reason is that I've been very upset all day because I did poorly on a test and doubt that I passed it.  Still, I'm afraid of getting no sleep and feeling terrible tomorrow.  Help!
