Winning in gambling will make your mood happy just as we get some rewards and we feel happy. These feelings are so great and we feel so energic and positive.
However, once we start to lose in gambling, we slowly move towards the sadness phase. If the loss continues and we keep on losing the money, eventually it can lead to depression.
Yes, I understand that depression is a very severe stage and it won't come at once if you are a new gambler but if you are not a responsible gambler, it is very easy for the gambler to lose his emotions and become depressed in life. Focus on other entertainment other than gambling for some time can be helpful in relaxing our mind and regrouping again to come back strongly in gambling with a strong emotion.
It's a natural thing, bro. You will feel joy and happiness when something good is happening to you and be sad if something awful is going on with you; there's nothing surprising in this. The first time you earn from gambling, your confidence level becomes stronger, and you feel happy. After some time, this confidence convinces you to get highly involved in gambling to win more money in a single bet, but the outcome is not always the same. At that point, when you are thinking about winning, you suddenly realize that you have lost a huge amount. This is the stage where a weak emotional person can fall into depression, which is the worst condition for them and a silent killer.
So, it is advisable for everyone to take gambling very seriously. Don't put everything in at once, and also don't gamble money that you have saved for your expenses. If you do it even once, you will gradually become addicted, and this gambling will break your financial backbone.
