Man, my life has changed a lot.

I guess I'm here because it's spring break and I need to lose weight again for a wedding. My college roommate has asked me to be her Maid of Honor in June. I've known about this for a while, but it's really creeping up on me. I've gotta fit into a dress that I ordered when I was ten pounds lighter (I had just gotten out of a 4 year relationship).
So....HELP!!! I don't even know if anyone is out there, but if you are... be my weight-loss buddy! Please!!!
