i dont have good tips, im still dealing with it but ill tell you what ive been doing
exposure therapy, but with coping mechanisms (ex: music)
"wanted" exposure therapy. so going to the grocery store is more of a "necessity" so finding unpleasantries is more likely because the unpleasant people have to be there as well, but a specific group/hobby, typically has a better more welcoming vibe (of course then you also have the possibility to run into the liars. "were so friendly and welcoming!!!!!!!!!!!!!!" oh, sorry you missed the disclaimer that states 'only if youre
exactly like us'. so still not grand, but closer)
but for me the biggest thing that "helped" was dire need. my 'ex'hus was in the hospital and i had to fend for myself, talk to docs ect. and i was mostly normal. i could handle it. i was proud of myself, and a little upset that he got out. im terrified of going back to the way i was.
so not good tips, but words from someone that understands. theres been many times i just wanted to sit down in an aisle and start bawling....
i completely get the perceived thing, sadly i think the best thing you can do is only pay attention to your bubble
