I'm generally not aware of the social life at my university, though I don't live in the dorms either. There are activities that go on, but I don't pay too much attention. Most of my social life is outside of college, like with friends, at church, etc. Going into college, I didn't really care about making friends, though some very good connections came about anyways. One friend knew me from high school, and we've talked and worked together much since then. I think once you meet one or two people you'll have an open door to many other people to socialize with.
There are definitely a few social advantages to college life. Sitting in my very first class session, I was amazed at how different it felt from high school. Everyone was quiet, undisruptive, and dare I say a little more conservative, and this was just the Freshmen introductory course! I think that's because most high school graduates in my area jump right into the local community college to try and earn far less expensive credits, and therefore probably a little more high school-like. People who are willing to pay for a university education tend to be very committed to what they are doing.
I think that the best thing you could do is focus on your area of study. If you have a passion for what you are pursuing, you'll do very well. If you're the type who gets a thrill out of learning (as many Aspies do), you'll find yourself doing abundantly well. This has been my main mental stabilizer for university life, just not worrying too much about pleasing people and being popular, and just preparing myself for what I want to be doing for a significant portion of my life. If it's something that interests you, it can at times feel very energizing.
My best advice for handling the social life is learn to be content with what you are given and the opportunity you have. I'm not saying you aren't, I just want to say that college is a great experience, and you're setting a precedence for the rest of your life. Strong social life or no, you have a chance to get something quite economically valuable. And it's those who work hard who will be chased by the employers after they graduate The friends will come too. You'll find a lot of like-minded people you can relate to and talk with.
Carpe diem!
