That's yours OP, and here is mine.
1. Keeping losses a secret is what makes the pain even more greater, find someone who you trust and tell them.
2. Avoid chasing what you have lost no matter how big the amount is, when you lost the money it is gone, forget it and move on.
3. Take some time off, go out with friends and clear your mind, and come back home to movies or video games.
4. When you healed, make sure you learn the true meaning of gambling, it is not a guaranteed way to make money, why not treat it as such? This will make you to never be reckless again.
5. Come up with a amount, and stay on that amount forever, if it is $1 so be it, always risk this $1 on gambling and make sure you don't do it everyday.
For points one and two, that is something I always do, first, whether the result is win or lose, I still tell my friend, there is no clear purpose but I do it just to share the story. And with the second, we should be able to understand that the money we bet is lost in gambling, that is something that must be accepted well because if it cannot be accepted well, the consequences will be even worse. In addition, there are many things that can and must be done when experiencing defeat in gambling, but the point is that we ourselves must be able to be self-aware not to insist on forcing ourselves to continue gambling to pursue victory in gambling.
