Losing in gambling gives you fear and tension so if loss in gambling just leave it if you don't leave it gives again losses only so gamble with intelligence and patience it is the only way to survive in gambling .
It is inevitable that when you gamble you will tend to lose and more you play more you will end up losing . So if you can bear that pain then its fine else if you have a weak heart then forget about gambling as it is not meant for you.
Definitely inevitable and it is funny that people despite knowing this will still be tempted to use what they have left to gamble after losing everything already. For someone in that phase, I would simply just call that an addict because I do not expect someone with the right gambling mentality to try to do something like that.
That action is more like someone who is trying to recover losses with the little they have left when that even ends up putting them in a more emotional state of mind.
