That is exactly what I meant to say which is why I added an edit. I for sure could have phrased that a lot better.
Now yes there are people who are undiagnosed for whatever reason (including some people I know that don't see the point after being diagnosed with ADHD, I know personally I had to have this conversation with my psychologist to determine if there was a point to actually do it at that point) that use that phrase and it gets a bit tricky.
But nowhere am I trying to imply that *everyone* is saying this.
