Base on my experience it is really hard to quit gambling specially when you are already used to it, before my parents will get mad at me becauase I forgot my responsibility as a mom also they sees me almost got broke because of being addicted in gambling. One day I realize to quit gambling and I really want to do it so by the help of my love ones and determination to change I now stop or quit in gambling .
In my own points of view, to quit gambling doesn't mean you quit yourself because we can find other alternate to gambling which we can make our life meaningful. We can set other kinds of habit to entertain ourselves. Let's make our family the true and meaning of our life.
I think you missed the point of the OP of quiting yourself its only when you think to quit gambling with all your heart and mind so its the way to quit playing gambling. The things you have said is a big help to get out of gambling especially your attachment and time to spend witg your family it more than playing gambling with fun and if its for money there's another way of earning and not in gambling.
