the biggest problem is you never want to leave gambling
People don't want to leave gambling because they already loss much money in gambling and they want win back their loses, but that's make them more loses. And it's gonna be a problem.
That is indeed true, IMHO. When someone tried to recoup their losses, it is clearly a big concern. You should not even dare to recoup your losses. Just let it go if you lose and even better if you stop right away. If you can't afford to lose, you should even gamble in the first place.
