You've probably seen this checklist (maybe in PDF format) before. It's called Everything is Awful and I'm Not Okay.
I used to have lots of everything-is-awful-and-im-not-okay days. Lots and lots and lots of them. Some times I'd have, like, a whole month of them strung together. Sometimes it was everything I could do to get home at 6 pm and crawl into bed. (Wheeeeee.)
