2:12 i cant sleep, school tomorrow HELP!?

Make sure you don't have a lot of distractions around you, like a t.v. or computer. If you do, turn it off. I find sometimes the more I think about having to fall asleep the harder it is, so you may want to try to get your mind off of it. Maybe pick up a book that you are not interested in (something that isn't going to make you want to keep reading) and try reading for around 15 min to help you relax then try to fall asleep again. If you all else fails hopefully you will be able catch up on some sleep tomorrow after school. Good luck!
