Yeah, that is hard, being away at college. But haven't you made friends with people on your floor, or in class, or maybe there's a campus club of something-or-other you'll want to get involved in? I had it much easier socially my first year of college, as I lived in a house that was kind of like a sorority. We had to attend a certain number of house events per semester, and just the fact that they had all sorts of activities, starting with an orientation and scavenger hunt all over campus the first weekend we moved in, got us involved.
Another thing about being Mormon, for those of us on the board that are, is that we automatically have a social group at church no matter where we move. So when I moved here to Boston--and before, when I moved to Chicago--all I had to do was go to church and start introducing myself to people, and eventually I found interesting people to be friends with. It's much harder when you don't have an instant social group like a church or a sorority.
So, Gemm, I feel for ya. But I do think you can, over time, find people with similar interests on campus. Most of the BYU people on this board know each other from TLE and related things like game night and writing group, which was how I met 42 and Brenna and EUOL and MoD, etc. Well, actually Brenna and I had a class together and she announced TLE, and I decided to go with her one night, if you want to get technical. My point is that I bet if you went to your school's website and looked up clubs, or if there's some other way of finding out activities on campus like a bulletin board, you'd find gaming people or book groups or whatever. I don't know what school you're at, but that's my general experience, having attended 4 different colleges/universities across the country, and it tends to be the same.
