Wits End

Not being able to sleep more than a hour or two at a time for three weeks is really starting to take a toll on me. I get upset at the smallest things. College starts again next Friday and I have a class at 9:00 that day, and if I can't get my sleep back I don't know what I will do:( I am at my wits end, my braking point. I WANT MY SLEEP BACK!!!! I need my sleep back so I can get my sanity back. Really I'm not asking for much. Am I?
