I'm not very hyperactive. On rare occasions yes. I feel my hyperactivity is restricted to my mind. Like, it's different than a hyper focus. Like, where other ADHD people might show outward hyperactivity I feel like mine just becomes an overwhelming amount of thoughts I can't even focus on. Its almost disabling.

If I was going to play doctor I'd say it's because of my childhood. I'm a male, but grew up in an isolated and abusive family.

I find this lack of hyperactivity is much more common in the women with ADHD that I have talked to. Again, just sharing thoughts, but I feel like this similar type of abuse that I experienced is very similar to how our society expects women to act. To be quiet and submissive. Which maybe leads to a coping mechanism to hide outward hyperactivity? I don't know, but it feels like that for me.

Come to think of it. My most outwardly visible hyperactivity happens when I hang out with women that have ADHD. It's like being comfortable enough to not keep it in your head.
