I am constantly moving my legs or my arms, I cannot keep still at all. Like right now my leg is tapping a hundred miles a minute. I don't know why I always do this but my parents, teachers, friends, all notice it. In school people made jokes that I was a dr*g addict because of how much I tap my legs or my arms or whatever.
I find it really hard to relax because of it. Is this normal at all?
