How do I know if I'm neurotypical? I have some challenges, I've done a few tests, but I could just be a lazy neurotypical bastard. I think if you go to therapy you can get to take yourself more seriously, look at the signs, self reflections and process that. Now that can easily lead to "I need to get diagnosed with XYZ". Just to be sure.
It's not about the rising rates, that could be explained in other ways.
You go to a testing center, not a therapist, to get a diagnosis. The online tests don't count. A thorough test will take a half-day or more, with tests ranging from conversations to Q&A to visual to a battery of multiple choice questions.
