Suuuuuuch common mis/comorbid dx's with autism! I hope you find all of your answers there. I was just dx'd this summer and my world is starting to make some fucking sense to me, it's a transition, for sure...but what isn't after the un-dx'd life? If you're not already doing it, I recommend joining online support groups (FB has a lot that welcome those questioning)
Sending so so many good wishes and hopes for your clarity and support to increase willllldly!
