2) firstly, I get why people SD. I did myself (kinda) to start with, and I think almost by definition, most late diagnosed autistics will be SD to begin with. But when I came to the conclusion that probably was it was after months of reading articles, watching videos, reading research papers, taking tests online and speaking to anyone I knew who might be able to offer an opinion inc friends and family. And that’s after living with autistic children for 20 years. That’s to say: I am pretty well..
