I am also a person who has experienced many defeats and it makes me sad and upset like you. But we don't recover from that loss by getting a big win, although there will be some gamblers who can get it. But still, it will not be easy and it may cost more money to gamble.
What you say is true and is a valuable lesson for us so that we will not repeat the same mistakes and can avoid big losses. So we better try to heal that sadness, forget it, and make it a lesson for us. We will definitely feel fine the next day and no longer have to feel sad.
if you can establish that realization you won't be dwelling with such kind of mistakes and it will give you a better overview not to repeat that same mistake, you can enjoy your gambling activities without losing a lot, if you know how to manage your funds and you already have that knowledge when to quit when you already losing decent amount from your bankroll, there's always another day to play, forget about pushing your luck and trying to recover your losses.
Give time to think and rest your mind to re-create a good strategy and a clear mind when trying to play again. Best to find the entertainment and relax your brain in not to think too much.
A bad loss must serve as a warning and a lesson at the same time that we should put limitations on betting and wager only the funds that we can afford to lose. We shouldn't put too much pressure on our gameplay but rather enjoy it with a positive mind. Losing is already a part of our gambling journey but we should still be smart not to chase it. If we're experiencing a loss streak, stopping or pausing will be a good help where we could breathe and relax for a moment. As long as we know how to manage our gambling funds, we can easily get over our bad losses by moving forward and learning from the gambling mistakes that caused us losses.
