I personally never cared much for the frat system. I did rush one frat while I was at State. They didn't elect to select me as a pledge and I'm not sure I would have accepted if they had offered. Of course at the time I didn't drink and wasn't much into partying didn't find much use for fads or appearances either. Sorry it didn't work out for you but IMO you may well be better off without them. Find something else for a outlet would be my suggestion. IM sports or the various clubs are good options from my experiance. I got into the SCA in college and probably devoted too much time to it and related activities but I've still got a lot of friends from that time period.
