Wow, I never thought someone else experienced stuff so similar to what I did. When I started college last year, I went to this summer camp before hand and I became friends with the people that I went to that camp with. But a semester later, I was pushed out of the group. Not intentionally, they were great people and would never do something like this on purpose. They just slowly stopped inviting me places. I remember one night, while I was walking back to my dorm, I ran into most of the group. They stopped to tell me that they were going to see a movie, but they didn't invite me to go along, and that hurt. And when I was invited to hang out with them, I would hear about all these awesome outings that they went on without me, which also hurt. At that point, I decided that I needed to get some new friends who would hang out with me.

So the next semester, I attempted to become friends with several people. In one class, I was lucky enough that a talkative person decided to sit next to me and we became friends. But I didn't have much luck outside of that. You could also say that I became friends with some people in a class where we had to work in groups, but it was the kind of friend that only talks to you in that class and never really wants to hang out outside of it.

But now I'm in the same boat as you. I had to transfer to a cheaper school because I couldn't afford the college that I was at. It's been a semester and I still haven't found any friends. And, like you, I'm not entirely sure how. College is so different from high school. In high school classes, you regularly talk to people who sit around you, but in college classes, it seems like most people either already have friends that they sit with, or they stick to themselves. So, something that I would suggest you try, and something that I'm going to try myself next semester is to find the people that are sticking to themselves and start a conversation. That's what that talkative girl who I befriended did, and it worked quite well for her. The whole reason they're sticking to themselves is because they don't know anyone too well, which means that they are wide open for befriending. And when you run into that person's already established friends, try to become part of the group.

Remember that all relationships are a two way street. Something that I learned at that first college was that they cannot be the only ones inviting you to hang out. You also have to invite them to do things, or they may think that you don't really want to be friends.
