Sorry you are in a funk. I think you have it right, all the stress you have been under, possibly your body just telling you to relax and take it easy. Rent some comedies. Be a vegetable for a few days. I always heard two weeks before it is worrisome. Go get a pedicure, I've heard they are fun, do something frivilous for yourself and read some trashy novels. Everyone deserves a break from reality.
