This is a very sad incident where it is very difficult to forgive yourself. But since you have been able to come out of that deep addiction, forget your past and start a new life and try to control yourself from now on. If you go to gamble again, then definitely remember your previous history and never use more money than you can afford. And I will give you an honest advice that is that you take a break from gambling for some more days so that your previous addiction cannot affect you in any way. And when you become completely normal, you should enjoy gambling if you want. But of course it should be to the extent that you can control yourself from there.
