I think, for me I had to walk away from people who were arseholes about it. So my ex, who would point it out in a not very kind, but apparently joking way (which screwed with my head as I thought I needed to go along with his banter, even though I realise now it was borderline abusive / definitely nasty)
My circle is much smaller. I'm 52 and I walked away from some acquaintances, no longer socialise as I cannot stand that feeling of being observed, criticised and exposed.
I can only be myself now as I don't have the energy to mask. So I only really spend time with my daughter and my parents. Obviously I go to parents evenings and things like that, and maybe say hello to neighbours, but I don't get involved. I might waffle a bit at my hairdresser, but she's also ND, so she gets it.
I don't know if that sounds extreme, but it's a lifestyle that suits me. No, it's a lifestyle that's saved my life actually, as I need so much down time, quiet space, time to decompress etc. I'm happier in my own company most of the time.
In essence, I only spend time with people who love and understand me, who will not make me feel like shit about myself.
