Hard stop and obliged yourself not to push for more, instead rest yourself and keep yourself busy to prevent adding more money to your bankroll, it's good if you know how to manage your finances as it will not allow you to lose more. decision making is very important as it will gives you what would be your next plan, just prevent making a quick decision without doing your good analysis, it helps a lot to keep your finances in good position.
Most gamblers really can't control themselves when gambling, they often add a certain amount of money into gambling again and gamble again when the previous gambling has ended in defeat, and this happens because they want to recover their losses and of course they do that because they don't receive the money they need. the stake was already lost in gambling. What you should do is, as you say, give yourself a break, especially your thoughts which can become confused if you continue gambling, but not all gamblers can do that.
I agree with what you say, as much as possible we must be able to manage our finances well so as not to lose more money when gambling. In fact, losses can be prevented by ourselves having awareness when gambling, as you said, just by making good decisions, considering the risks with the decisions we will make in order to minimize the risks that will occur, it depends on us ourselves who are gambling.
