While gambling in the reasonable threshold that you have determined, or only to your deposit values and you do not make a deposit anymore after losing it is not a problem, I understand how our emotions are provoked and our principles begin to be destroyed because of that, logic does not work as usual, it also often happens, but the most important thing is not to make a deposit after the first deposit is complete.
Losing consecutive is not a strange thing, accepting defeat is gambling in gambling and is a form of gambling in a responsible manner.
Losing control of emotion, then action is not strange and with anything, when a person loses control, it starts to be bad and even turned out to be nighmare. To succeed, you must beat yourself first by controlling yourself from emotion to thinking, decision and action before you can beat other people in the same market or in gambling.
If you fail at the very first essential steps, you only can have losses in both short term and long term that is surely not what you want but you can not avoid it by unable to control yourself.
