I have been having something that seems to be an anxiety attack since 6:00 p.m. last night. Erratic heart rate (goes from normal to racing, with a little bit of everything in between), I occasionally find myself short of breath.... I don't know what to do, though. I mean, I'm stressed, obviously, but I'm not panicking or anything. I'm calm, and I thought I was dealing with finals/bar/job situation all right. This is really frustrating.
