Melissa, I can relate. I have so much that I should be doing, but just feel that I can't do. Studying is one of them...though I had a dream (nightmare?) last night that I had missed two exams each in two of my classes, in fact I hadn't even shown up for a single lecture for either class all semester! I awoke in a sweat, and felt much better about my academic neglect. It could be worse, lol.

I wish I had real advice to give you. It's a difficult problem.
