When I was a freshman in college, I worked, went to class, slept, and wrote; not time for much else. In a discussion one night with co-workers about what we were all doing for the weekend I made some self-deprecating remark yet again about "oh, my EXCITING night watching movies in the dorm room." One of the other girls who liked to go out a lot laughed (not pleasantly) at me and said, "If it's what you like to do, it's exciting enough for you, I guess. If you don't like it, get off your chair and go out and find things to do. Do, or don't; but why do you care what other people think of how you spend your recreational time?"

And, it's true. Of all the people you will ever know, you're the only one who has to spend all their time with you. Entertain yourself with fandom and keep one eye out every so often for commenters and posters in your shared spaces, and you'll find like-minded fans. I guarantee it.
