(aren't you in Seattle, too?)
I was freakishly moody and incredibly irritable all the time after dd was born. Is it possible you are depressed? I never knew that depression could manifest itself that way until it happened to me. In postpartum doula training, I heard a panel of post-PPMD women talk about it and it hit me like a truck. I'd be happy to talk or PM with you about it, or I think we may even be neighbors...
I am wishing you all good things, I know how hard it can be to feel this way - no one feels a lot of sympathy when depression turns you into a raging bitch. (At least i was, pointing no fingers at you!)
