I'm definitely not, as you put it, the stereotypical "hyperactive", but on learning more, I realized how many little tics I have that I do but in very masked ways so as to not draw attention. But that aside, there is 3 different diagnosis for ADHD - primary hyperactive, primary-inattentive or combination (both to some level). Despite what I said about tics, my diagnosis was for the inattentive side of things. "Head in the clouds", "daydreamer", etc.

It's all relatively new for me, it wasn't something I really seriously considered until a year or two ago (and I'm in my 40s now), despite having a brother who was medicated fairly young and a father who displays many of the same traits (never diagnosed though). It's definitely helped me to know this, puts some puzzle pieces in place, so to speak, and gives me a path forward toward managing something I didn't really realize I needed to manage, but was having a significant impact on my life regardless.
