I can tell you about my experience and how it was for me. When I first started playing, I made small bets, and every loss was a significant stress for me, I was worried about losses, and it was difficult for me, although, I repeat, my bets were small. I think that many players perceive gambling in this way, no one wants to lose money, everyone wants to win. Therefore, it is difficult, and you need to be prepared for this, that there will be losses, there will be stress, and you need to think in advance how you can get out of this state. That is, you need to be prepared for the fact that stress cannot be avoided.
It is an eternal truth that if we had not perceived these things in advance that there would definitely be losses in gambling and that this is what we would face most of the time, then the stress we would have felt after losing here would not have been so much.
And I have also gone through many situations like the one you went through from the beginning, but now these things have become more acceptable to me and because now I spend a very small amount of funds on gambling which does not give me much stress. And I think everyone should spend such an amount which does not give us mental stress.
I also lost a lot, but it was quite rare until I realized that I did not want to repeat such an experience, because it was very noticeable for my wallet. And even knowing the experience of other players, I wanted to try it myself, although fools do this. Now I use a specially allocated amount for the game, which I will not exceed, because I already understand what the continuation of the game will lead to. I understood the subtle point and the problem of many players, they just promise themselves each time that the bet is the last, but they make another one after another, but the last one should mean that after we make it, we must immediately close the game, and not find reasons to continue.
