I have have similar symptoms as u do. Just like the trouble with concentration, fidgeting, constant daydreaming, not finishing school work etc. I also have trouble paying attention and I tend to get overly excited/hyper over simple things I find fascinating.

A friend of mine noticed my behaviors and led me to this website so I took the quiz and I got 100% but I never really took an actual test or diagnosis at any hospital so I just keep things quiet for awhile until I'm rlly sure I have it.
