I need a mental health week (or two)

I love my job. You guys have heard me say it before and it's true. This week, however, is not one of the reasons why I love my job. If my job were a vacation package, they would not have pictures of this week in the sales brochure. Or perhaps it's just me and Monthly Depression Week (MDW)? It doesn't really matter why...I just want to be anywhere but here.

Outside of work, I have so many things to do and not enough time to do them. Perhaps it would help my mood if I left at lunch to run errands? It's worth a shot. Besides, my high-maintenance team member is being extra-needy today and that doesn't work well with my MDW - it would be very bad if I were to explode with rage and frustration, wouldn't it?
