Do you know why some get depressed in the gambling, it's because they're not calculative when you come to gambling, I know very well that in gambling it has to do with something good, but when you fails to make a research before gambling you gamble to regret, because most of people who regrets after they have gambles, most of them fails to use what they can afford to gamble and stake in gambling, the most important thing in the gambling is to know amount to be use to gamble so that when you lose it will not affect you you.
I would not even partake in gambling or register on casinos if my experience drove me to feel depressed, I cannot imagine someone paying or sacrificing money in order to feel miserable with their choice. It does not make sense to me.
Those who feel depressed, either because of their ignorance or because they actually believe they can defeat mathematics behind casinos are the ones who need to stay the furthest away from them, in my opinion.
It is normal to feel some regret, but talking about suffering recurring depression because of the way one could gamble and the objectives behind it is a completely different scenario.
