Update

After writing the long, ranting, weepy post of above, I went to the ladies' room on my way out for a walk. I have my period. I haven't had my period in two months, which means I've got two months of really cranky PMS. That would explain my mood. Sigh. Anyway, I took a really aggressive, fast-paced 15-minute walk, and now I feel better. Things still suck, but I'm going to continue to work hard and keep up my end of the bargain.
