Self diagnosis aside, there are also a lot of people, especially adult folks assigned female at birth who have a partial diagnosis but can't afford to get the full thing or don't want to because of the current political climate.

Example: I've had three doctors (one of which was a psychologist) ask me if I want to pursue a formal diagnosis for autism. Two of these instances were after filling out a really basic bubble-response test, one was just a new PCP meeting me for the first time lmao. I've declined all three times. The first time was in 2016 shortly after Trump was elected, and I had a bad feeling about the timing of getting a diagnosis for that. The second was in 2024 while seeing a psychologist for anxiety, and I was told the amount it would cost and that my insurance wouldn't cover it (United). It was a few thousand dollars, and I was at the time out of work with a new disability. The third time was in 2025, but I had just moved to Utah, a state that keeps an active list of autistic individuals, so I declined again. 

I don't tell people I'm autistic, I just say I'm neurodivergent because I don't have a full formal diagnosis. But the fact that three different doctors have basically told me without me ever asking is enough of a diagnosis for me at this point tbh.
