The new relationship between my butt and the couch

Okay I'm seriously depressed -- I think it's a combination of work stress, reduced daylight, and a combination of feeling both "stuck" and "can't-keep-up." I don't know when I became such a working stiff, but lately I go to work, get my butt kicked, and then come home exhausted and want to do nothing but consume myself to sleep with TV and snacks. It's all pretty pointless. And I don't really savor my own whininess, either...I just wish I had some kind of game plan to change things, but I don't, and that just makes me doubt my own resourcefulness. Ugh.
