My parents and siblings know about my lifelong social issues, depression, anxiety, self-esteem problems, and all the ways those have ruined my life. But AvPD specifically? No. I don't see where it's helpful to get into the diagnostic weeds with them. They get the basic issues. Sort of.

I told an old friend about my depression. But not the rest.

That's it.

Obviously I talk about it here, and it's on my profile. But I keep this account anonymous.

I think Snap66's advice is good.

I don't do Facebook or social media in general, so I won't comment on that. Sorry I don't have anything more helpful.
