friends talkning behind each other's backs

my friend A and my friend B were arguing and they said some hurtful stuff to each other and I tried to mediate but friend A wouldn't take friend B's apology. after some more stuff we sort of fell apart and I went around and realized friend A is talking to others about me and B behind our backs. it's been months but I can't stop thinking about it. idk like no matter how shitty you are or were to me id never do that to you why would you do that to me? i just dont really understand cause we used to be rlly good friends too. like wed eat toether and play games together and it was one of the few friends i made in a while too cause its kinda hard. and i just idk what to say. it was a stupid argument but like friends argue and idk what im supposed to feel just that its been hanging in my head like A has called me a bitch and wanted me to die and said that they hated me and said some false stuff to other people and like i dont have the full record but i dont even know how much they said cause i shared a lot of stuff with them like pretty private stuff and idk someome like that would tell others right? and im jst lowkey panicking cause idr want other people to know. idk its been months and no one has bothered me but im jus still kind of scared.
