I would say go for it. To catch up socially, just go to a lot of parties and talk to people, but don't try too hard, its OK to be less talkative in your first few parties, but don't avoid interaction either.

In a frat some guys will like to bust your balls and you will have to come up with quick responses. Don't worry about responding eloquently, you will get better over time. But make sure you don't laugh it off, agree, or self-deprecate...bust their balls back. It is all in good fun. This is how your social skills will improve.
