When gambling becomes an issue and a life problem then quitting gambling is not quitting your life its getting your life back! I personally cant understand how people let themselves get to that point where they loose everything for a game. Its supposed to be a fun activity not ruin life for it.
This is like getting back on track as you have moved away and in order to win the race one has to be on life track. So putting oneself back on track is not called quitting the life which you have said rightly. Also I would insists that if you want to gamble play it but only for fun and or not do it for money as it can become an addiction and will be difficult for you only.
