For me the best part about college was a (game development) club I was heavily involved in. I met a lot of good people and had good experiences. I still speak with some of the people from that and do some activities with them. This is not exclusively a college experience though. You can do this later, whether that's with coworkers or other people. There are tools out there to find people with similar interests, for example D&D is a good one.

College forces you to interact with people with similar experiences and interests, which is why it's conducive to this, but it isn't the only place it happens. You'll be fine regardless. It sounds like you just need to get past the stage of meeting new people, which is the hardest part.
