S.A.D.?

With the days getting shorter, and the darkness lasting longer, my mood sinks. I'm going through one of those blah phases that starts in October and lasts until April. I think it's called Seasonal Affective Disorder.

I'm behind in grading, too. Like two weeks behind. Students keep asking me when I'll give back their papers and tests and I feel guilty that I haven't returned them, stressed out that I still have to grade them, and angry that I have 130 students' papers, tests, quizzes, and homework to grade.
I just want to crawl into a hole and never come out.
