I think this kind of discussion needs a supervision of a suitable specialist not on forums where anyone can say random words.
It's still better to discuss with this kind of issues to also help other gamblers to narrow down the main issue of being lonely which leads to addiction. Addiction is a serious matter which needs to be handled by some specialist and you definitely right with your concern.
I don’t think everyone who does gambling is addicted because of loneliness and dissatisfaction. Orhers do it for recreation and self enjoyment. The feeling of satisfaction upon winning a game cannot be measured by any means. Addendum to that excitement in winning is the fact that you double your money in your money pot which will prolong your time in the gambling house.
