In most cases gamblers cannot control their emotions when they lose. In fact, the most important thing to control your emotions in gambling is that the player who can do it will not become the only victim in the future. We can see in many cases that there are many gamblers who do not control their emotions when they lose but they want to double the bet to make up for their lost money. But whenever they start committing such wrongdoings, they suffer more losses and become very emotional. Moreover, one must always control oneself in gambling and stop oneself when one loses money until one can control oneself, one can never be a responsible gambler. Between winning and losing gambling there must be a stop in between which can lead a gambler to a good stage in the future but if emotions are not controlled then it will surely lead to losses.
Many gamblers do not even consider the possibility of controlling themselves at all, what they want is to obtain a great deal of fun and profits from gambling, and what is ironic from that posture is that those that are looking for both of those things very often obtain neither.
Since it is impossible to obtain any fun while they are losing so much money, and despite the overwhelming evidence that their wishes are impossible to accomplish, many gamblers will not give up hope until they lose every single dollar they had to their name.
Sad truth, emotional gambler will push instead of accepting that loses they will keep trying their luck and most of the time they'll end up losing everything and only regret are the witness with their suffering, emotion should not be tolerated if you want to keep yourself away from losing such amount that you can let go.
Just place a bet with the money that you are willing to lose and accept if the fate of your bet lose then quit and call for that day.
It helps to avoid losing more which is not on your budget for your gambling activites, emotion mostly leads you to keep losing more money.
