"Peers don't know what they can't see/They can't see inside of me" refers to the fact that his disability is hidden and the rest of the world don't see his reactions unless he flips out or does some other behavior that he doesn't want occurs because of said disability. He's impatient to find out why he's behaving this way, and he wants to find out why he is behaving like this.
