Join extracurriculars. Join a bunch of them. Just keep going to the meetings until you figure out which ones you like. Then stay in those ones, and even if you don't make friends for the first month, I can almost guarantee by the second month you will. When you make those friends, they will invite you to parties, and you might even wind up moving in with some of them. This will also help you learn to socialize, which will be valuable for the future. I recommend being active in at least 3 or 4 of them - that may sound like a lot, but it's not - they most only meet once a week, often for an hour or less, and I guarantee you can find the time.
