Yes, this is something I deal with as well.
It's interesting because as a kid I got diagnosed with ADD, and my sibling who was more physically hyperactive got diagnosed with ADHD. My parents thought, and thus I did also for a long time that the 'h' difference was due to his physical energy, but it seems unrelated.
I've wondered if I am on the spectrum also but I don't match a lot of the base/core traits, although I feel ADHD or ADD alone doesn't explain some of my, ahem, quirks either.
I want to again stress there was no malice behind my question, just interest in trying to relate through my own experiences. Thank you again for answering.
