Thanks for the link (mono and LR)
I hope that getting this down and hopefully normalized hormones will bring you some peace.
There's an old English saying "there's nothing as daft as folk" . I think this fits your incident with these people quite well.
The only other thing I can suggest is "look for the opportunity in all of this." Sometimes it takes a while for the waters to clear.
I'm like you. I haven't got time for dishonest people. It does keep the numbers of actual, physical people in my life limited somewhat, especially now that I'm working from home and there are no kids around. Still, I prefer that than wasting my time on 'stupid people' and their dramas.
Oh and just remembered something else that might help. Other people's ideas about us are not our business. Our business is to live our life to it's maximum potential. In order to do that we have to able to unhook their fish hooks from our backs otherwise they will just keep reeling us in. I know it's easier said than done.
Take care of yourself
