I am no counselor in any stretch of the imagination, so please take what I say with a box, not a grain, of salt.
It sounds like you are not happy at all: with your school, with your campus, with yourself. The fact that you have thought about transferring schools, as well as the fact that you could not find
one organization on campus that piqued your interest make me think that you are not happy.
Sororities are not a panacea. A new member doesn't automatically realize her hidden potential upon receiving a bid. College should be a time of personal growth. Concentrate on yourself, take care of yourself and do some soul searching. Maybe you will be happier with a fresh start at a different school (sometimes Moms do know best

). I hope you find your way and are happy. Good luck!
