This thread must have been opened by OP when he suddenly made a big bet and lost!

Let's sympathize with him together, but let's hope that he got the most valuable experience, the meaning of which is already remembered a thousand times here in "Gambling" - you should not play for such amounts that you cannot afford to lose.
But I should point out to the delight of the OP that I think everyone has had the experience of losing a lot unexpectedly.
And everyone is well aware of the nasty feeling that comes. But I must say that for me even the first time it passed rather quickly. I was not very upset for a long time, then I completely forgot about it. True, he became more careful with his passion. Learned to slow down. And don't be blatantly stupid.
