Addiction in gambling is really hard to get rid of it most of the time your temper is more attractive to any gambling once your a gambler you will die a gambler and you can't change that tho the greedisness to earn back what you've already lose chasing after your lose will be result as your become poorer and get nothing at the end untill you will lose your mind thinking where you gonna get money for your self.
It's sad to see because another human being died just because of an addiction that shouldn't be there in the first place. The thing that is hard is that you are against yourself and nothing shall ever interfere with you because it's only you who can stop the temptation. Better decide for yourself and be happy with what you have now.
