i know it won't be easy and you've already heard the best advice - get up, quit, take a break, etc.
sooner or later your tilting will settle down the more you play.
you'll realise it's all in the game and there's nothing you can do about it. just remeber the times it was the other way around when you won with the lesser hand. haha we've all done it - for pot odds or maybe the halibat, lol.
i know i don't take the game as serious as i use to because of that reason and saved my moniter in the process. hahaha

good luck and peace..........................
