brother to be

As I move into initiation next week I am questioning whether or not I really want to be a member of this Fraternity. Some of the guys seem to be cool with me but I get the itching feeling that others just flat out don't like me. I am trying my hardest to just fit in correctly with everyone but nothing I seem to do works. What should I do? If I don't join then I will go back to knowing literally nobody on this campus.
