Genuine Question, Have you felt the friends with whom you have lost touch and know too much about you might cause you a problem ?

okay so not many but one of my friends knows wayy too much about me and we have lost touch since 2022, we don't follow each other i have deleted all my messages with her and honestly we don't know anything about each other now But whenever i think about it i sometimes feel like she knows too much about me and i have talked about that stuff here as well but since my identity is hidden i don't mind it but when i think about it , i get shivers what is your opinion about it , Although we don't have any bad blood it's just we lost touch with time that's it
