No friends yet, first breakup brain. How do I break the cycle?

Hey Guys I hope everyone doing great So pretty much long story short things didn’t worked out with this girl and we broke up and it was short relationship and my first relationship and she already thinks me as casual friend or acquaintances that I can see while I’m still like moving on tho I don’t want her back but sometimes I do feel like I want her back

and it’s almost been 8-9 months and since we live in small city, I still see her here and there if I’m at mall or just grocery store ( where I work )

It just That I still try to see her social media and whenever I see her I just always goes in spiral and feel I’m just keeping myself stuck in this loop and I don’t have much friends since I moved here not long ago

I also feel sad(!?!) that I don’t have talk to much girls and just to think like that I will fine and not think about her since I’ve people that care about me but no of this is in my life. I just what should I do and not try seeing her social media and think that no one will love me and she only loved me in way I wanted to be ( I guess my anxious attached also kicks in here )

So honestly like how just like handle this overall
