I've had some problems in the last couple of weeks with getting on tilt when things start to go a bit downhill in the game.
In the first game, random effects converged in just such a fashion as to bloody my character with one random, unavoidable effect, and knock them to dying at the end of that same round.
In the second game, I suggested a course of action that the party ended up using--that was then criticized by the DM as a bad choice of tactics--and also was criticized by the DM and a fellow player for some of my strategy in battle.
In the first game, I actually left the game because of my anger--and the second game, I did get a little upset and was near leaving, but stuck it out through. I don't want to be known as the 'angry' gamer--I like these people, but things just went south. What can I do to help keep my gamer-temper under control? What should I do when things turn negative?
