GatorKate-
I'm sorry you're experiencing some negative feelings towards your past sorority recruitments. I saw something another poster said that I thought was important to repeat.
If you knew that you had messed it up yourself by saying you weren't sure and then they put you lower on their list, is that going to make you feel any better? No, you're probably going to feel worse because it was your mistake.
If you knew that it hadn't had anything to do with what you said, and they put you lower on their list just because they didn't want you badly enough, would that make you feel any better? Probably not, because it's going to mean they wanted other girls more.
It seems like you're happy in your chapter now. I don't know if it was one of the ones you originally referenced or not but I can absolutely promise you that the way to experience the best time posisble with the chapter you are in now is to give it your all and stop the second thoughts about your freshman rush. Things tend to work out best for people who make the best of the way things work out. Good luck
