Marcus, the only advice I can come up with is to follow the advice given to me once, when I was in a vaguely similar state:
1) Take frequent showers.
2) Keep breathing.
It isn't much, but it works, I guess. And usually, when life cracks me upside the grape, I remind myself that things have been pretty dismal before and I always survived and was glad for it. Even if the pain you're in seems unprecedented, the same trend will probably follow.
Sorry I don't have anything better for you. You've got my sympathy, anyway. We've all been there.
