Online forums for autistic people
Hopefully there will eventually be some online forums specific to the NYC area, for members of local groups, and hopefully there will eventually be some online forums for autistic workers in specific categories of careers / occupations / jobs.
In the meantime, here are the two most popular message boards for English-writing autistic people, in general, all over the world:
These message boards are moderated by small teams of volunteers.
These message boards allow (and welcome) pseudonyms -- unlike Facebook. (While lots of people use pseudonyms on Facebook too, it's against Facebook's official policy; and Facebook occasionally cracks down, occasionally requiring people to prove their identities or else lose their accounts.)
Autistic in NYC will not list Facebook groups/pages due to Facebook's policy of requiring legal names, a policy that I, the owner of this site, regard as a violation of the privacy of marginalized people of all kinds, including autistic people. Autistic in NYC also will not list any other forums or social media that require legal names and/or photos.
Featured page: Where to get an ASD evaluation as an adult.
It's not easy to find psychotherapists who are qualified to diagnose autism spectrum disorder, especially in adults.
On the above-linked page is a preliminary list of places where some members of local support groups obtained their diagnoses. Soon this list will be updated to include many more places and, for those already listed, more information about insurance, other reduced-cost options, etc.
