I can't sleep.

It's after 3 in the morning. I can't sleep. I'm so worried about things. What's going to happen to me in the hospital? What will happen when my unemployment benefits run out? How will I find a job with my health? If I find one, how can I possibly keep it.
Little things are driving me crazy. What will I do with my dog when I'm in the hospital. No one but me seems to be worried about that. He's so little and the world is so big and cruel. I look at him and my heart breaks, thinking about leaving him here alone while I'm in Chapel Hill. He doesn't understand. What if something happens to him? What if something happens to me?
I've got to go to sleep. I'm exhausted. And horribly depressed.
