"But now I'm in college and I want to change. I want to be social and party and so on." Here's the thing you have to understand: the ideas of introversion and extraversion that you hear are usually a bit of an oversimplification. Everyone has an introverted and extraverted side. It's just that one of them is always dominant. With that in mind, there's nothing wrong with developing your extraverted side. But it sounds like you're trying to change from being an introvert to an extravert which is futile. I know that I (as an introvert) wouldn't be able to handle a fraternity: I'd simply be too drained by the experience. Instead, learn to enjoy being introverted and engage your extraverted side from time to time. You'll be much better off that way.
