Take your a** to the party but just be "yourself." If you drink then just drink a couple. Go up to the few people you know just to say hey and tell them you can only stay for a few because you have to get up early. Tell you you were hanging out with some other friends and they caused you to be late. Anyway, that gives you a few minutes of face time, allows everyone to see your pretty cool because you don't show up, get **** faced, and break things. Then you're out of there and you were seen by others. The next time the other people are having a party and see you it will increase your chances of getting invited thus giving you a social life.
Go to the party but do it on your terms. A quick in and out and a few handshakes!
