Overwhelmed by thoughts

Since I moved to another country I lost some friends. They just cut me off, deleted me from social media and I don't hear from them anymore. I know they were kinda fake, talked about me behind my back (which I still can't get over) but now I'm really worried they might still talk about me and ruin my reputation in my hometown. That makes me feel really anxious...

Also one of them started being so cold and ghosting me while I was still in my hometown. I suppose she was jealous because I got a driving license faster than her (and she thinks she's a god for some reason) but our other friends also got faster than her and she was treating them normally.. Idk what did I do and I can't stop myself from analyzing it :')
