Sometimes it's tuff to keep the emotions together.Come into a pot with the best hand, then get beat on the river with someone who called your raise with duece trey, sucks, but it's poker and you just have to deal with it (I know I can't that well). There have been many of times I've wanted to break stuff. I'll do the same, take a couple hands off and regroup. If I still can't control it, I leave. No point in wasting money.
