We've said it countless times that it isn't always good to gamble putting your hope and emotion on it.Things don't just hurt,it is the expectations you expect that hurts you.
Gambling is a risky game,which we know,but the fact that you will invest your emotions in it is something that's going to continue to be a pain in your heart.It is this so called reason that has made so many person avoid gambling,Everytime you put your attention on games and is so anxious about it,just be ready to lose, because it doesn't always end up well.
Gambling should be for fun and I don't see why one will be emotional if he is gambling for fun and also using an amount of money that he can afford to lose because that is what will give you the upper hand of controlling your emotions.
If you cannot control your emotions when gambling with little amount of money, there is no need for that person to gamble in order to avoid emotional trauma. If you are gambling for profit, it is bad because that is when your losses will affect you emotionally.
