I never want to go to parties, and I'm a pretty sociable guy. Salesman by trade. But I always dread the small talk, thinking I'll be bored if there aren't people I know there. And I almost always end up having a great time.
Point being, it's too bad you didn't go as you'd likely have enjoyed yourself. The good news is that you're in college and there'll be plenty of parties and eventually something will happen that will get you to walk in the door. You'll be fine once you do.
