It is not just gambling but everything of which someone is addicted, is not easy to give up. You are the person who can help you at first, you need to make yourself assure that what were you doing till now was wrong and is bad in all perspectives then seek external help. It needs strong will and clear vision driven by inner will and you can get rid of gambling addiction over the time.
Sometime it is not easy to change yourself. You also need some support to empower yourself to overcome all sort of difficulties. But of course, the first and most important is that you must take the first step and willing to put in effort to change, then the other support will be useful to help you to change.
Yeah, agree! Even if how many times they help you to stop from gambling if you don't have willingness to do it, you will still stuck on where you are. We need to sacrifice our wants to stay away on what we have used to. DETERMINATION is the key to stop from gambling.
