I see it wrong if you can't handle your emotions thats it
Not only the emotion but also the money that you are pulling in your pocket when you gamble. Things are becoming wrong when it's too much and as for gambling, when you are gambling too much and you can't control not only the emotion, the priorities, the money and other important things that you need to remember then you are affected in a wrong way.
There are times that we loss control in gambling, instead of spending only what you can afford to lose, you become too aggressive and risk more because you want to get back your loses that is why you chase. That decision is not well think of and most likely it will result to a bigger loses which in the end you will just make regret it, stay calm and discipline in gambling because that is the only way it will make you safe.
When you are too emotional when gambling, you can lose all of your bankroll when you are not careful. Being too emotional makes you rage bet because you want to chase previous loses and that is a bad thing because there is a big risk and chances that you are going to lose.
