Exactly! Rehabilitation camps and doctors are just there to help and guide you to overcome your addiction to gambling because the final decision is on yourself and you will serve as the test if you can really overcome that challenge. As far as I know, only people who are really serious about changing their lives are the ones who overcome their addiction but if they are not serious.
Addiction or excess of anything is bad. First thing is, we must try our best not to get addicted to gambling or anyother such thing. But if you are addicted to anything like that then one must consult his family or talk to doctor. But yes that's only possible if someone consider it a problem and wanna get addicted to it.
