You make a valid point regarding people being reluctant to acknowledge their addiction. It's a major step and frequently veiled in dread and denial.
Things can begin to change, though gradually, when others close to the addicted person step up, show up, and engulf them in a cocoon of support. No, it's not a short procedure; it's sensitive, progressive, and slow. The addict may begin to understand the effects of their addiction. And you're right; that's where the magic happens. the gradual recognition, acceptance, and movement towards change. All of it is slow, but it is very necessary
It's possible that the initial modifications and shifts will not be noticeable. But these little adjustments can begin to grow into something more, something transforming, with constant love, support, and encouragement. Change is not only possible; it is probable with the proper people and the right support. It is a journey, a long and winding road
It's okay if it's too late because it can still be done if they can admit it and are willing to start changing it. After all, it's all for the good and changes in their life. After all, it's better late than never, especially to change bad habits and get a better life.
When they recognize their gambling addiction, they can start to make small changes so they see what they can do. This change may take a long time, depending on the mental readiness of each addict, but it is worth doing to get a better life.
Once they have made these small changes, they will begin larger changes and get used to their new activities. But it's only temporary and building a new habit takes time. So those who still have the drive and enthusiasm to change, will be able to continue well until they can finally cure their gambling addiction.
