Might I suggest going for a walk, or seeing if you can get your hands on a punching bag? I get the need to release frustration, but put that energy into something positive for you. They're too far out of the reach for anything negative from you.

And, like I said, work on making yourself less effected by what they do. If surviving the 2008 recession and whatever the hell the current economy is has taught me anything, it's I should have started that second thing years ago.
