Hello Lindsey!
I am going to have to agree with what everyone has already said. I was kinda like you in that I was very quiet and not too self confident before rush. As hard as it was to put myself out there and be outgoing and talk to all these amazing girls, I am soooooooooo happy I did it. Going through rush was totally not something I would normally do, but I have loved every minute of my 'sorority life' since then. Plus, I am more confident in myself and am WAY more outgoing now, which is definetely a plus!Ultimately, this is your decision, but I think you should go through with it!!
I always say its better to regret the things you've done instead of the things you haven't done.......
