That is one of the things that causes depression, emagine using money that was meant for another thing important for gambling and loss it in that process. Of course such person will not be happy.
I think you're very correct about that, and of course losing the money that is meant for important stuffs to gamble is not always that easy for one to sake it out of his head. Though the very first time that the temptation will come you will still find it very hard to figure out that you're being tempted, not until when you finally fall for the temptation that's when you will still realize that you are being tempted in the first place.
Because of this, we must be able to recognize ourselves better so that we can avoid problems because in the end if the impact has started to lead to addiction and depression about it, the situation will become more complicated.
Depression is not a trivial problem that can be cured easily because it is a matter of our mentality and thinking so that this will actually add new problems because we must try as much as possible to stop the effects of addiction that we have in gambling, we must also be able to cure ourselves from the depression that is experienced which of course this requires something more because depression if wrong in action can end fatally.
Start to recognize ourselves before doing something including gambling because after all we clearly understand that by us who recognize ourselves then indirectly we know the limits of ourselves that we have. That can be an effective way to suppress when we are gambling because we are aware of the capacity of ourselves.
