Self-control will be enough to get out of gambling addiction. You can only take a decision or take help from others to get out of gambling addiction when you feel remorse. Otherwise, there will be no hope of getting out of any addiction through others or yourself.
To get out of gambling addiction, I will give you the best advice that you should focus more on self-control in the beginning and quit gambling gradually instead of quitting it completely. If you decide to quit gambling suddenly, it may not be successful. What you need to do is reduce the amount of gambling. Continue to reduce the amount of gambling in this way, eventually you will succeed in quitting gambling completely. This process may take 2-3 months.
I admit that once a gambling addiction is established, it's very difficult to stop unless the person is aware and accepts the situation. This can only be achieved through encouragement from others, but through self-awareness.
I've experienced this, and even in the face of adversity, I couldn't shake my gambling addiction until I finally realized I was just enjoying it. But I still couldn't stop gambling completely. Now, I'm free from my severe addiction and gamble only for fun.
