I was diagnosed pretty late for all of it, especially considering how transparently obvious the adhd and autism was. My parents asked all of my teachers if I had ADHD, every year, all of them thought that I didn't. I only ended up getting diagnosed at 11 or 12. The autism, I kind of figured out by myself, I got on a waitlist for testing at 15, a year later I got the diagnosis. This is all especially strange, considering that I'm a white American male. It is pretty good that I was able to be diagnosed, instead of the psychologist just deciding that I'm bipolar or neurotypical, as many in marginalized communities are.
