Pity is the ego trying to keep you focused on it. The ego is a destructive asshole. It's a negative, petty story you keep telling yourself. If you stop thinking about it (by being fully present) it'll start to lessen itself. (I realize I made it sound simpler than it is... but its not as hard as it seems)
I hope this is helpful.
