I can so relate to this, although we're in different countries and at different stages. We're about 2 weeks from getting our keys, yet I still cannot relax.
I don't know anything about the house-buying process in the US, but from your and Rae's thread I get a basic feeling that it's much more stressful than I ever anticipated. I did not know there were so many stages when things could go wrong. In any case, good luck, take care of yourself, eat well and I wish that the days until the next stages pass fast and as stress-free as possible... which, I know, seems impossible now, but one thing that kept me going through all my house-related events throughout the years was the thought "this too shall pass". Sometimes all you can do is breathe and wait, once you know you've done all you could.
Best of luck!
