Being able to manage your emotions when you lose when gambling is indeed a very difficult thing to do, especially when they use their last money to gamble, of course this will make them emotional. Yes, for those who have experienced many losses in gambling, it is better for them to stop for a moment so they can evaluate the game they are playing so they can improve it the next time they gamble. For some people who have experienced a gambling addiction, it certainly won't be easy to stop, but they have to try to control themselves so they don't fall into other bad things.
This is more reason why we shouldn't focus our energy in gambling whether winning or no winning, gambling should be taken as fun like even if you lose it should be taken as fun.
And again don't use money that you planned to use and do more important things to gamble as you might regret it after the outcome fails you. I know no one is happy when they lose but they can control their emotions when they lose because they took it as fun
