Ok, the not-so-dramatic conclusion to my tale...
The next day was bid day. It was a little disappointing because I already knew what my bid card said, while everyone around me was anxiously awaiting their fate.
The card said ALPHA DELTA PI!!
I got on the bus to the Pi Hut and the rest is history!
I should add that ADPi took a pretty serious risk extending me a bid. My gpa, as I posted earlier, was not wonderful and I came without anyone's recommendation. I don't want people to think we don't have a strong house--I was absolutely at the bottom of my Alpha class, which was full of awesome girls with impressive resumes.
Anyway, I got my grades up and became very active, and now here I am. So maybe they just saw potential.
