I have a kind of similar "problem"... when I'm going out, I often have some unsolved problem that I can't stop thinking about... And so it happens that I'm sitting quietly, with a beer in hand, at the bar and think about trees and forests and forests of trees whose leaves are trees, and people start thinking that I'm depressed or bored or weird. My solution: not caring about what other people think. But I realize that's not really an option at work. (OT.: Hello everyone, this is my first comment, but I've been reading HN for a while.)
