That makes sense, maybe it's true that they don't see other things that give the same pleasure, and indeed in my opinion there are still many other things that are more fun that don't require money to get pleasure. In my opinion, if they are already heavily addicted to gambling, of course their lives will be destroyed, because people who are addicted to gambling tend to only think about gambling and maybe they always prioritize gambling in their lives, and of course prioritizing gambling is not a good thing, because like that it will make them only focus on gambling, even if they don't have enough money but they will try something to be able to make money so they can do gambling again.
I think the main thing is to have your own awareness, before your family or friends who provide support, I think that's the main thing.
That's because they can no longer feel the pleasure of other things and only think that gambling can provide that enjoyment and pleasure. However, if they are willing to stop for a while and do other things well, they might be able to feel that there is a pleasure to be had when they do other things. And if they do other things more often, they will abandon gambling to do those things more often. At that time, their focus will begin to shift and maybe they will try to start reducing their gambling activities because they have found something different that can also provide fun and enjoyment.
They will also see that they can save money when they do other things and can use the money to buy food to enjoy with the people around them or their friends. This will give them another "taste" so that they will slowly change and reduce their gambling activities.
Yeah, that is one of the typical factors in addiction.
People get their "high" after doing certain behavior, it can be an activity, not a substance, and it will also create addiction on the brain.
That is why gambling is regulated worldwide. It is quite addictive.
