You are right about the mind of gambling-addicted people being blind which is what makes them please their lust. I can remember when I was a drinking and smoking addict. My mind is blind from seeing the side effects of what I am doing while it is open to the special feelings that come with the intoxication but I never blame someone for it and I can say that's what helped me.
Because of this, I said that gamblers who blame others for their addiction are irresponsible and will have a difficult time recovering.
Will have that difficulty as they can't accept the truth that it was their actions that brings them to that situation, though once they realize and accept it, help can come around and back them up, gambling is a form of a risky activities if you failed to control then you are not by far to experienced addiction, it's always good to treat it as form of entertainment since you'll not going to hook yourself that much and if ever that you lose you can move forward and let the amount go, treating it as payment for having the enjoyment that you gain while playing.
