Do I have some type of mental disorder ?

I am in 7th grade and right now i have to rush so here are a few things. First my reading level is supposedly S but I constantly read adult material. I study quantum physics but others in my grade dont know what that is. I am currently reading about then hadron collider and came up with some theories of dreams. I obsses over quantum physics and have a vivid long term memory. I lack at social skills and hate crowds. I make hardly any eye and I appear stoic. Only smiling so I would not be misread as cold and rude. I dont not attention in class. I get bored easily and have lot of insight and logic that all I can point for now also have little friends hardly none
