This is weirdly common, from what I’ve heard. You’d think it would be obvious that a disorder (or neurotype, or whatever you call autism) requires accommodation, which requires self-advocacy, which requires being allowed to know what’s going on with you.

I grew up having no idea I had ADHD (probably on the spectrum too, given that my kids both have it and ADHD and autism are almost like smoke and fire), and instead just had no idea what was wrong with me. Because that’s the support I got, being repeatedly asked “what’s wrong with you?” for thirty years.
