Yeah, I really don’t think it’s you who’s the problem at all. In fact I don’t think anyone is the problem.
It’s quite possible that they just happened to be the group of people to hang about with in mutual classes but you just don’t have any common interests with them, or if these are old friends from your high school days you could just be drifting from them. I know it’s easier said than done but don’t feel bad about it because these things happen. It’s just part of life!
As to the solution, perhaps consider getting involved with nearby groups or small communities that have similar interests outside of college. If you’re open to that idea, you’re likely to get more genuine friends than you know what to do with, then you can concentrate on college and getting an awesome career at the end of it all.
All I can say is please try not to lose hope and I understand that you like to be accepted and belong somewhere; we are social creatures after all.
I hope this helps out in some way, and feel free to throw me a message if you need to
