Organic Chemistry Stress and related things.

I'm tired. And feel rather blah, and I just don't know.  One of my friends has recently been rubbing me the wrong way, and I was in their presence for a little while today, and that wasn't helpful, and I think I didn't buy a textbook thing I needed for my Orgo Class.  Because I thought that the Study Guide and the Coursepack were the same?  I guess.  Also, because the bookstore was supremely confusing about what books I needed for what class, and what those books actually looked like.  So that's comforting, that I've made it halfway through the semester without a book I'm required to own.  And I feel rather ready for the exam, but everyone else has done so much more preparation than I have, and they're still freaking out about it a bit.  So that is starting to scare me a little bit as well.  And I was in a good mood, a great mood right up until I decided to study with people.  So that was a stupid decision, in retrospect.  I'm going to go listen to my music really loud and work on a puzzle.
