Don't forget that you are probably carrying around enough anger to sink a small island. Leaving a company when have been there too long often leaves a rim of bile in your mouth that needs to be excised. Until you dump some of it, you may find that you are constantly getting into arguments, gritting teeth, being convinced everyone is a jerk, etc. Might I suggest two simplistic things: go watch a couple stupid movies on a big screen and pound some softballs. The movies should be the type with more deaths than words and the softballs should be at a slow pitch batting range (like Malibu). I know you play sports resembling small wars, but there is a purity of inflicting violence on small, easy, relaxing balls that smush just a bit as you club them.
Anger, Movies, Balls
It is worth a few hours to see if I'm right.
