Night owl

I just spent the last hour and a half lying in bed trying to sleep, but I think that I'm less in the mood to sleep than I was when I started. I lie there restlessly, really wishing that I could go to sleep, but then I become frustrated that I'm not falling asleep, and I think that that keeps me up even worse. I feel pretty much wide awake right now. The only real difference is that now it's later and I'm angry.
