The amount of times this sentence is heard in our house, along with the dramatically exaggerated waving of arms, would definitely qualify for a sitcom catchphrase.
You see, reader, I'm what they call "late-diagnosed".
"Late" is relative, of course. For ADHD, "late diagnosis" can mean anything from above 60 for those above 60 to 25 for those who are 25. For Autism, some guidelines even go down to 12 as "late".
My own ADHD stamp (with the bonus traits from a handful of other neurodivergent conditions) came at 37, with the fancy PDF attachment. We already knew, we just didn't know know.
Once confirmed, though, not one week goes by when I don't do, say or remember something that so clearly reveals a neurodivergent trait that's always been there.
