What's your priority, being in "a sorority" or being somewhere you feel right? From your post, the two are not the same for you. Only you can decide.

If as others have said, the chance of a bid somewhere you want next year is slim, are you willing to accept the idea you'll not be "successful" next year? Choices have consequences, and only you can decide whether the consequences are those with which you care to live.

Boo-Hoo! Get over it! These ladies chose you and you are being really unfair to them. There are other girls who would LOVE to have what you have right now. Get OFF the computer and go spend time with these ladies. This is just shameful.
