Attention Deficit Disorder very weird

ADD I suffeer,
don´t bother,brother
But why in the hell can I see a documentary of two hours, or read a book,
or talk to people(which if they don´t talk about things I like they really bore me)
I´m a weirdo. Why do I pass from one subject to another? Without the bother
of one subject related to the other subject. Also knowing the consequences of
what I wrote or said and then, shut down and completely go space out. Kind of weird.
