When you cannot stop gambling based on your emotions, it means that you are gradually becoming addicted to gambling which might be counter productive or a harmful. I think one should start seeking for help when his emotion becomes a motivator in gambling.
I think becoming a gambling addict is not the point but the ability of the person to still become responsible despite being a gambling addict.
There are lots of professional gambling players that are obviously, so much addicted to gambling but look at them, still doing better outside their gambling life.
It's hard for others to still keep being disciplined and responsible gamblers but with the right approach, everything should be good.
A person that is addicted to something can still be a good person. However, that person must undergo certain treatment in order to fully recover and regain his overall well-being.
Being a gambling addict can affect your life in so many ways. If you are addicted in gambling and has no self-control overall speaking, then most likely your life will be ruined by your bad habits. If one of those bad habits is borrowing money, doing illegal activities just to earn money to sustain your gambling needs, and other negative things that's related with it, most likely you'll just end up sabotaging your growth. However, if you just so happens to be dependent on it but has the means to actually control your urges, then you're not a hopeless case.
Proper diagnosis, intervention, and treatment are all they need to regain their whole life back. Because if you are addicted, whether you like it or not, there are really certain aspects of your life that will be impacted by it. If you can prevent and minimize it, the better it is for you.
