Do I have ADD? Please answer!?

I can't focus, no matter what I do. I wiggle and fidget constantly. Right now I'm kicking my feet, and I didn't notice until I just looked. I lose EVERYTHING. I have a rough time falling asleep unless I'm dead tired, and I have endless energy. But oddly, I'm pretty smart. No excelerated or AP cles, but I do well in normal, grade level cles. I'm very creative, love art and music. But I zone so much! I just stare at the floor, the pencil on my desk, whatever. I bite my nails, kick my feet, twirl my pens, flip pages in my book, doodle... whatever it takes to keep me calm and "focused". Do I sound like a child with ADHD? I am 14 and a girl
