I would echo moniques thoughts. Whatever any underlying issue may be it would be hard to address it, or even recognise it, while we are still in action.
I would also add that it is important to realise that, whatever might have lead us to addiction, that addiction is now also a problem in it’s own right. If we stop gambling, sort out whatever “caused” our addiction, we would still be compulsive gamblers and unable to return to “normal” gambling. It is a progressive problem with no reverse gear I’m afraid.
