I Feel So Off...

Yes, it's 2:20am, I'm still surviving on 2 1/2 hours of sleep, and I feel very very off. I doze off a lot normally, but I'm zoning out like every two minutes now. It's really weird. Then I just feel weird in general. It's not a very good feeling; it's like there's something wrong with me. And then I'm crazy tired, but I REALLY don't want to sleep. Blah, I'm going to go try to sleep (I doubt I can though), and hope stuff gets better in the morning. I doubt it though, I've been feeling off since Sunday... What the hell is wrong with me?
