You can say this about most if not all mental disorders.
I don’t know what to tell you. I’ve had it my whole life. I didn’t believe it was real until I got older. I have an extremely hard time focusing and listening. I get distracted far more than others. I am hyperactive, it’s actually painful in a way not to move around sometimes. I have weird urges to move in times I know I should stay still. And I am extremely impulsive.
I get some people use it as an excuse and it might be over-diagnosed. But my entire childhood was teachers giving me a hard time because I can’t focus in class, i move around and stuff.
I have tried my best to control this, but it’s really hard. My parents had to fight with most of my teachers to keep me in the normal class because a few teachers wanted to put me into special ed. My grades are always good, I can read the materials and grasp it but I can’t listen to my teachers.
