It's really difficult trying to navigate situations like that on sites that are all about quick responses and actions. Do you think you might be able to compartmentalize a little, if you can't at this time remove yourself from FB, for example ? Could you put on " snooze " those who tend to push certain buttons ? Maybe join a group or two that don't include anyone of your friends list and that are about things you like and/or care about ? Maybe take a break from communicating with people who know you/you know, unless necessary.
