the worst moment came when I was not able to control myself, I bet all the money I got, which I should have won and finally lost big. This as an experience if we have won it might be better to go home and play again next time.
In my side, the worst moment is when the time that I give my everything but there is nothing in return. I lose all my hope that everything will fall into each right path again.
We must always remind our self that in everything we do, discipline and control to your self is very important.
Maybe the "everything" that you are saying is that you give your money but you lost am I right?? If yes, then you are not the only one. There are some gamblers who are willing to give everything they have just to gamble. They can't stop themselves from gambling especially if they lose a huge amount.
Self control is for me the best attitude we need when we gamble.
