I shoudn't be up now

I have a final, in 4 hours, 45 minutes. Of course, I have to be up an hour before than to get ready and be coherent for it, so that makes it 3 hours, 45 minutes. But that doesn't matter. I can't sleep. I don't have a lot on my mind, not any more than normal, anyways. I don't understand it. Somebody hates me and wants to keep me awake. I'm so tired I don't even know what to fucking say anymore. I came on here...for no reason I guess.
