Tired

I have given up getting a good night's sleep for the month of November apparently. I go to sleep pretty easily but then I wake up in the night and am consumed by thoughts of the dissertation and other pesky worried. I am tired to the bone.
I had planned on getting a chapter to my adviser by Christmas but at this point I can't see that happening. Every time I read a book I realize how much more I have to go. I also need to get on some research trips but I'm not sure quite how to make it all happen.
I need a little break but can't afford to take one.
