I quit bookface many years ago because of exactly this reason. Well, this and the fact that FB has absolutely blown the trust of keeping all this data on us without it being spilled into the universe every few years. Or worse, used against us politically.
Anyway I wish I had a solution other than "delete the account and don't look back," but I don't. I will say that life goes on and those people in your life that really care will find a way to communicate with you. And the ones that don't? I don't miss them at all, really.
