i really think you need to learn to play through the emotional swings in the game. if you need to quit cause youre on tilt and youre going to hurt yourself, great. but quit THAT session or not, the fact that you are having such a strong emotional reaction is a problem in itself that needs to be rememdied. play within BR management guidelines, know that the money you have 'exposed' on the tables is like the tip of an iceberg. sometimes it melts sometimes it grows, but each hand is a new day and must be approached with icy analysis. never let results affect you emotionally, really work on it. lose a pot, take a smoke break, reload and get back to work.
