It seems to me that he has not only a mental disability, but an extreme stage of gambling addiction which is why he is so irresponsible not only for his losses, but also for his huge debts. In my opinion he needs compulsory treatment for gambling addiction as he can't handle it on his own. I was very surprised how in his latest video he asks a complete stranger to him, blogger Melstroy, to give him over half a million dollars to make a few more bets so he can pay off his debts.
For gambler to ask someone to give him such outrageous amount so he can use it to stake bets and use the winning to offset his debts is sign that gambling addiction have really eaten deep in his mental health. He really needs help from anyone around him to come out of such addiction. At this level of addiction, the best thing to do is to send such gambler to a rehabilitation center where he'll not have any access to gamble again. I think with such measure, he'll break free from gambling addiction
