I'm sorry for him, I'm posting its case not to judge. Meanwhile, it could be a good lesson for us to not repeat the same mistake.
I too am sorry for the guy, I hate when people lose too much money to gambling because I have been in the position before and I know how it feels, he will really be depressed right now, but the best is for the person to just take off his mind and move on, if there is life there is hope.
We should use the amount of money we can afford to lose, not even only that, it is also better to take gambling as fun rather than a way of making money. Let list so rapid because he wanted to make money through gambling which is most likely not possible.
