I think the first step to overcoming gambling addiction is to ask for help from the family, if it is still not resolved, then we can ask for help from
a rehab center. But the problem is that not all countries have rehab centers for people who are addicted to gambling, most rehab is available
for drug addicts. But basically how to overcome gambling and drug addiction in my opinion is not much different. So it is very possible to cure
gambling addiction in rehab for drugs. But we can also ask a psychiatrist for help. My friend once recovered from gambling addiction by asking
a psychiatrist for help.
If his country does not have a rehab center, visiting a psychiatrist will be the solution to solve his addiction to gambling. But his family will be the first help that he should ask to search for a fast solution before he visits the psychiatrist. It is really hard to cure the addicts because that needs an effort from him to solve it. Maybe curing gambling addiction is not hard as drug addiction, but it is still hard to do if the victim does not want to change his habit.
A rehab center for gambling addicts? I haven't even heard of such things. If you ask me, I don't think it would work. Gathering all gambling addicts under one roof isn't a good idea IMO. It's better for the addicts to stay home and take prescribed medications while being supported by their families. That's when the support from family members counts big time btw.
Maybe in the other country, the name of that rehabilitation will be different. Still, I think the country will have rehabilitation for the addicts and use different methods to cure the addicted person. Of course, prescribed medications will be necessary and needed. Still, if the addicted person can talk heart by heart to other people, especially to the psychiatrist, that would help them figure out why they become addicted. It needs an open mind from the addicted person to know how they can live like other people without becoming addicted to gambling.
