If you feel like people who do this kind of thing are just few and they are stupid, think again. This is so prevalent in the gambling industry that certain countries like Australia even had to impose a ban on using credit cards in gambling sites and sportsbets to make sure that no one's digging their own graves trying to gamble their whole life away. So yeah, real PSA for everyone out there, don't gamble if you can't afford shit. Gambling wouldn't give you anything but entertainment, the money is never a guarantee and by the moment you login your acccount/step inside the casino, you should already set your mind to the fact that you're not gonna win anything and you'd probably end up empty-handed after the ordeal, but don't let it get to you and just gamble for the sake of enjoyment.
I understand that these people don't know what their actions are all about, until they've landed into a bigger trouble. He was experiencing a fake love for his newly funded blackjack game. Despite losing, he felt taking loans would be a better form of extending his fun time. The goal was not actually getting his funds back, but to keep on being excited. Some utilities, aside gambling can cause these things, unless we take a break or run out of funds, the brain won't relax to this level of realizing we've been down 2 years back. He was a newbie, when he joined gambling, self control wasn't there, and a good adviser to stop him, even the lender should have stopped him. Although in such a condition, no word of mouth is able to change the person's mind or action. People who lend gamblers money, can have a rethink or do further research before giving out the money. Well, I don't know the current source of income for OP, but he'll need to find a better paying job, to fasten the pay back time. Predicting it'll take him 2 years to clear his debts, can cause him a breakdown, as he won't find actual fun, till he clears it all. The sooner he pays back his debt, the better for his mental health. Then, he shouldn't hide things from his closed ones, opening up is a great way of solving his problems.
