The more I think about it, the more the psychology makes sense. There was a week over the summer when I felt really great again, when I was on vacation, and I figured it was because I was at the beach, getting sun, eating fresh seafood, etc., but I was also vacationing with family and close friends, so the psychological angle was a lot better, too. I've been feeling better this week, and - lo and behold - one of my good friends who graduated and moved came back to visit Sunday. So...there you go.

On the one hand, it's nice knowing there's nothing physically wrong with me. On the other hand, it's kind of frustrating knowing that there isn't much I can do besides wait it out.
