Do Friend Groups Change?

This is pretty sad to write, but I feel like I have no friends anymore in dental school as a D1 out of state. I used to be in a pretty large friend group, but I no longer want to associate with them as a lot of the people have drama with each other and aren’t the nicest. Since I’m not from the area, I don’t have friends outside of school and it feels pretty lonely. Since we are already a few months in, everyone is in pretty tight friend groups and I don’t know what to do or how to proceed. Im pretty friendly with everyone but that’s about it. No one really goes out with anyone but their friend group anymore, even our school event last week no one was there. I know I am there to get a degree, but there is a hole in my heart as I love to host events and study with other people. Do friend groups change at all? It feels like it’s a little too late and I’m just disappointed in myself.
