Anyone else late dx and suffer from insane imposter syndrome?

I was diagnosed at 27 by an autistic psychologist, after self identifying for about a year. I am female and very high masking. I recently had my dx corroborated by a new psychiatrist I was seeing for an adhd consult (not a full eval). So it’s been.. nearly three years and I still ask myself “well am I ~actually~ autistic though?” Like what if I just have something else and desperately convinced myself that I’m autistic for the sense of community or comfort of an identity or something?

I’m pretty low support needs (most of the time) and I feel like the rhetoric I see from autism parents, professionals, and just general consensus outside of the nd movement can totally get to me.

It’s a weird in between place to be when you’re not “autistic enough” but also not neurotypical enough. Sucks sometimes.

Disclaimer: I know being high masking is a privilege, and having low support needs is also likely due to privileges I have in many areas of my life. I don’t mean to complain about that at all. Just the weird limbo feeling of not being enough either way.
