I think that something difficult not to want to do is like stopping eating, or stopping doing a basic activity, but if I see that my abstention can help a person, why not do it? and play in the casino just when that friend is not online or do it differently in a physical casino or something, but if you have to have a little patience, addiction is a very serious problem, it is something that I don't know how to classify I think I would have to say that it is one of the most difficult things a human being can suffer.
So I start from something, we shouldn't be selfish people, if a friend needs us, what's the point of stopping playing for a while? I believe that divine blessings come after a very good action, and what it feels like when you do something good for someone is a great feeling, I believe that that is what we should always consider, and thus be able to have better things so that they can be happier the people.
If you can do it it will be much better because you can help one person, but making active gamblers aware is not easy because they need greater attention and it will be much easier for their closest family to do it. Even if you are a friend, you can also help heal. Recovering addicted people must be in a special place because there they will be trained psychologically so that they no longer have hallucinations of getting money from gambling. Without involving smart people regarding psychology, it will be very difficult to cure them because training the awareness of active gamblers is not easy because they have high hallucinations about games to make money.
If someone is in need and you are able to do it, there is no problem helping a friend who is addicted to gambling and I am not saying that you cannot help cure a friend. But rather the priority of the person who is more important in curing them is their immediate family. If we are talking about decisions, it might be a little more difficult because hoping for approval is a noble act and it is very difficult to make the discussion wider.
