Losing friends after moving sixth form

I’m in this group that I’ve been in for the past 3 or 4 years from literally around year 8. I recently moved sixth forms to one that had better grades and honestly I just wanted to switch it up, and I didn’t want to go to a mixed sixth form. It sounds stupid but I feel like they don’t want to be friends with me. When I went out with them, they only talked about our old school (where they go for sixth form) and boys that go there, they didn’t ask me how my school was or anything. Whenever I would mention something, they would quickly shut it down, or go on about how they preferred their school. (For example, this is so dumb but I said I liked that I could bring my own notebooks and they were like: well we don’t have to get our own, that’s so much effort, why would I want to buy my own etc.) I feel a bit lost, we were playing a game the other day and they would just talk about something I was completely unaware of because they had told each other at school; and obviously I wasn’t there. They were even complaining that people that knew me had asked them where I was, as if it was so annoying to explain that I moved school.
I get that I’m the one that made this choice, but it’s just so weird and awkward, because I have nothing to talk to them about. When I mentioned a new friend I made they started saying she was weird and clingy when in reality I’m literally the clingy one without any friends right now.
It’s so annoying and frustrating, because I feel like I have no friends or at least, close friends, because everyone I met at my new school are new people that I don’t really know, and my old friends don’t even seem to want to talk to me.
Do I just like.. move on with life? Try to talk to them? I know if I try to voice all this they will probably say it’s not like that, but it really feels like it.
