When your gambling activity affect your emotion too much, that's not a good sign and I think you should stop for a while.
Evaluate yourself especially your gambling activity, why it can change your emotion because I think your emotion is changed like 180° means that you lost something that more than you should.
If you have better limit on how much to lose, I dont think your emotion will change that much.
I cant deny that I was like you when I was still in my early gambling journey, luckily experiences teach me a lot and I can learn from it.
Gambling can really affect us, where we can become overly emotional because the gambling we do is not in accordance with our own expectations, gambling will result in defeats more often than wins, and if we cannot accept the reality of the fact that we will lose more often then It's clear that it can trigger our emotions, it's true what you said, we should stop for a moment to calm our minds and calm our emotions, because gambling done with emotions will trigger big losses and everything will become a mess. It's not surprising that many people get emotional about the gambling they do because they themselves can't respond to gambling properly.
That's good, having experience and learning from experiences that have already happened is a good thing, because by having that experience we can learn lessons from it, and maybe those who are addicted to gambling can stop if they have experienced something that is true. it slapped them so much that they realized not to gamble excessively, and could learn from the thing that slapped them.
