This Place is Poison!!!

[dirtywordplay]

I had an amazing week at school. I have been on top of everything, enjoyed time with friends, did well with diet and exercise...got my health checkup, got a job... Immediately upon getting home, my mood plummeted. I've been crabby, nit-picky, up and down, and just all around pissed off. I know it's not my fiance that is the issue, because we went out last night, and I had a great time. Also, I got home before he got off work and as soon as I walked in the door, I hated everything.
I don't know what to do, we BOUGHT the house. And now it kills my mood this badly? How in the hell do I compensate for this strong of a feeling toward our house.
