Sadly, I won't be able to get to my doctor for another month (when school ends), but thanks for the suggestion,
englishteacher. I did talk to her about my ill-managed anxiety when I was home over break, and she suggested increasing the dose of the meds that I'm currently on, but I can't pay for it out of pocket and don't know if insurance would reimburse my 'rents for it (huzzah for Big Pharma, huh?). Hopefully I can get things sorted out over the summer.
Leacon, what you're describing sounds exactly like what I'm feeling right now. I didn't immediately think "depression" when it started because usually I can "feel" when I'm depressed very acutely--the feeling of depression is unique, and easy to identify. I guess this might be different because it's brought on by stress?
And I guess.... I'm working really hard at being happy.

I SHOULD be, and I'm plowing through the difficult stuff as best I can, but it takes a lot of work to be happy when your world is turned upside down over the course of a week. Meh.
