OP, you don't have to blame yourself for your loss; the reality is that you have just lost the game, and that's what gambling is all about. Either you win or you lose. But if I were you, I would probably have staked the game twice; the first one will be for your original stake, and for the second one, you will just have to reduce the odds either by removing the last games you added, or if you still have doubts on the two stakes, you might want to make it three by reducing the odds again and stake the remaining ones. For example, if you place a bet on 15 sports games for #1.7k, you can repeat the same bet, but you will just have to remove some games and stake on the rest. You can do it up to three places, so one of them will definitely 😁 give you a win.
In gambling and before gambling one should already know what risks one will receive later, winning or losing is clear, that is the answer at the end of the game, and to be honest one must be able to accept whatever the end result is. When you gamble you lose in the end, I'm sure that under these conditions most people will not be able to contain their curiosity and if they are one of the people who are easily provoked then they will take out all the valuables they bet. Here I see that you are advising someone to enter the addiction zone by trying it several times until they can get the victory they expect. But on the other hand, we must realize that this is a gamble that prioritizes the principle of luck, and if someone does this repeatedly, then I'm sure the downturn will befall him.
It's simple enough to avoid prolonged defeat, one just has to look at gambling in a healthy way. I mean don't chase victory too much there because there will be very many negative impacts that you will feel in your life, and also don't be too ambitious, just use gambling just for fun when you feel bored or stressed because of work. This looks better and can be used as a factor in one's self-control in gambling.
