I finally went and bought a sunlight lamp, in an effort to haul my mood out of the sewage dump. This morning was the first time I used it, so it's a bit soon to tell, but I think it might work! At the very least, my mind was tricked into thinking positive thoughts, and I had energy and happiness all day.
I'm not totally convinced yet, but I'm hoping for good things. Surely one day of light therapy would not make such a difference. Perhaps the stars were just all aligned properly, and no one looked at me weird today. Who knows. I don't care, I'm just thrilled with being less of a bitch for a change. I'll keep you updated.
