How do you stop caring what those who cannot care think about you?

This is not an attack ....or even criticism ...regarding anyone with any particular diagnosis...(or anyone on pc) I’ve had good friends with “severe” bpd (the title of the book..) and traits of NPD..

My question, how do you stop caring what those with an inability to care think of you? All the FOO had an inability to care about me (“family” of origin)

I will not blame the young cub Fuzzybear for “not being good enough” or worse. I could not have pleased them or been accepted by them whatever I did. I would have been punished whatever I did or did not do,

I have CPTSD so please no comments like “stop living in the past” or “move on”...

I try to live in the moment but due to my mh issues sometimes I have flashbacks etc...

I am working on this...

I have not (yet) found a tremendous amount of quality support from professionals in this forest irl...
