What do you do when...

you're really upset with a person, and there's absolutely nothing you can say or do to her/him about it because of the situation. And by the way, when I say upset, I pretty much mean angry. Good old fashioned swear word anger. Yes, I am angry. Read something recently about positive ways to manage anger. I always thought that simply letting go and catharsis was the best thing. Apparently, release actually raises your stress levels. And that it's better to simply walk away. Walk away. Except what happens if you can't walk away? What do you do then?
