You have to get some other hobbies that don't involve luck and money in the same action. You must find some other way to spend time that is ideally free (nothing is really free bla blah but you get the idea). You can just watch some movies or join a gym and do some exercise, it's good for stress. Gambling addiction is a real problem, almost any alternative is better.
That is great point. Every alternate to gambling addictions would be better in many ways like financially and also in psychologically. I do see gambling addiction as a psychological problem so we need to approach it emotionally to get rid of it.
Yes gambling addiction must be a psychological disorder to gambler. But I believe this disorder does not need any peculiar treatment other than deviating our concentration to other different things/hobbies.
