I think I have ADHD PI with hyperactivity of the brain???

I fidget and can't sit still but I don't feel like im driven by a motor or bouncing off of the walls. That's kind of how I was when i was a kid.

When I turned 12 and hit puberty I guess the hyperactivity went from mostly physical to mental.

Is this possible? I think its the reason i have racing thoughts, get irritated and agitated all the time.
