I've been feeling blah and unmotivated and unenthused by everything, too. In fact, I have a test today in school and it's taking all I've got to make myself study. It's an easy and interesting class... I think part of the problem is that I haven't been taking really good care of myself physically. My sleep schedule is messed up. That messes up my eating schedule. Then my energy level gets messed up.

Have you gotten out of your normal routine? Hope things are going better for you now.
