I think to quit gambling, it is important to find a positive activity to replace the time and energy previously spent on gambling. Find satisfaction in activities that promote development, such as sports, learning new skills or developing intellectual interests.
Let the changes be challenging, but only with effort can you succeed and enjoy a fulfilling and creative life.
Factual, when the mind is preoccupied by positive things you will find no time for gambling. Apart from finding positive activities to occupy the mind, the victim of gambling addiction also needs to relocate to a new environment.
Staying in the old environment where they have gambling gang will not alleviate the situation. Although, they could bet online but they will no longer have motivators.
This is also an important part of the fight against gambling addiction. Changing your social circle allows you to get out of an environment that is dragging you down. In a new environment, a former gambler can make new acquaintances who will not encourage the desire to gamble. I think it's important to surround yourself with people who support your drive to overcome addiction.
There are some people that you can't ask them to come live with you because you want to help them battle their gambling addiction, it depends on their age and if they are still very young it could be possible, gambling addictions are also on different levels, someone who was influenced by friends is different from someone who was born in a family of gamblers, the battle to stop their addictions will be different and more harder too.
I have a brother (just family friend) who mingled with these type of friends from a very small age around 8 years old till 24yrs old and now that he is an addict we are forced to change his location and get him a job and thins went on for two years and one day he just vanished, we thought something bad happened to him so we headed to the police station, to cut my story short, he went back to that state to get back with his friends and all the money he had gathered for the past years was wasted on gambling, not too long he was shot dead by cultists, that's when we knew he was a member of the evil fraternity all along.
Some addictions can be stopped by the person if they are determined to stop it themselves, in this world, so many people don't even know where they belong, they don't know what they want in life, they are just among the living is all.
