Perhaps you could try joining a team (sports, intellectual, or political movements) at the school. Push yourself to be active in the ___ that you really enjoy. It will help pass the time more enjoyably, and help you make friends with those with similar interests.

You feeling like you don't fit in, due to your sexuality and family finances, I can understand. I would imagine that there is a counselor on your campus. Maybe you should check into seeing them sometime. I believe that you accepting your sexuality is the key. And that takes time....so, having a counselor helping you work through your acceptance could help a lot. (In my opinion, anyway.)

Very best wishes to you!
