wanting to affiliate

I'm an initiated member of a sorority that happens to be top tier at UCF and I want to affiliate with my chapter but I'm scared of not fitting it with the girls or not even given the chance to affiliate. I've had family members and friends that go to UCF and they haven't been able to tell me anything positive about my chapter. I'm willing to do anything to be a part of my sorority but it's just really intimidating. Does anyone have any advice?
