Something's not right...

I've been enjoying my Day O' Freedom very much, and by that I mean doing as little as possible. Though I did get around to doing the dishes, cleaning the bathroom (gross), participating in an online 'professional development' course and getting the week's lesson plans done. But somehow I've gotten this strange feeling of unease in the past 20 minutes or so. I don't know if it's because of an email from DB (he feels it's unlikely that I'll get a great deal of financial aid) or just dreading going back to work tomorrow, but my good mood has vanished. Weird.
