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.
Very true because there is nobody that is losing and they will be happy regardless of what there reasons are for gambling. Both the individual that is gambling for fun and those gambling for money will both get depressed when they are losing. The difference between the two user is that while the gambler doing it for fun can control his emotions and take a break as you have said. The gambler that is doing it for money will go into depression and from there he can turn an addict because he would not quit or take a break as he should have done but will continue to gamble and put himself under pressure that it will be very hard for him to come out from. Gambling has impact on our emotions but it is not that difficult for us to have control when we are gambling, we just need to be observant.
