help?

This is an anonymous website, everything should be taken with a grain of salt. You're in college now, time to start living how you want to instead of being worried about what other people are going to think of you.

There are top tier houses and there are bottom tier houses but no one cares what you are in... That's just stupid..

No one will be ostracized for being in a bottom tier house - you get ostracized for being a douc hebag or loser. That has nothing to do with what tier you are in.

Ok 1) would you really want to date a guy who didn't like you because of your sorority? He sounds like a real keeper. 2) you're an adult now and are capable of deciding for yourself which sorority you personally like because you get along with the girls, not what you think you're supposed to like. 3) I am in a "bottom" and I went to fraternity functions, I went to cup, and I went to tailgates because the guys like me not my letters.
My point is this process is about finding your home. Not everyone is supposed to end up in a "top" chapter and that's fine. You can either trust the system and find things to like about the chapters you have left on your list or miss out on the great experience of being a Carolina Greek. The choice is yours.
