I hope you get your "official" diagnosis. You already know who you are, so it won't change you. But it might unlock some doors and get you additional support.

Because we have nonexistent social support for autistics in the US, getting diagnosed here usually changes nothing for you. I paid for evaluation in my 30's and was told I was "high functioning".

It helped me evaluate my interactions with others. I realized I wasn't masking as well as I thought I was. I understood then why people always thought I was "strange", "eccentric", "freakish", and difficult.

I still sought to hide my "true self" in public. I wanted to be accepted and "normal" to those around me. I wanted to escape the bubble of isolation that surrounds me even in a crowd (I'm 6'2" and ex Special Forces, with my affect people move away from standing to close to me).

I hope that a diagnosis means more these days in terms of unlocking real support for you.

Best Wishes.
