First off, God loves you, messy house, crappy attitude and all. Secondly, you're going on my very special prayer list.
Thirdly, as so many have suggested: Get to the doctor! They can give you even a "little" something that will help immensely until you get yourself back on an even keel.
And here's something that usually works: Imagine you are in say, a Wal-Mart Super Center with 45 minutes to wait. You don't want to spend any money, so you're not looking to purchase anything right now. What department will you go to for the 45 minutes and what will you look at? - That's your current passion. Pursue it!
As to the pity pot, we all "need" to visit it from time to time. But when we forget how and when to flush, that's when you get to the doctor. Man! If I didn't have my hormones, I'd be the wicked witch of the west.
Most of all prayer will pull you out of this pit. I'm honored to send a few your way. Hang in there; we're all here for you. Do stay in touch.
