It can easily be said than done to get out of it immediately. That's where the struggle starts for the addicted gamblers, they barely get out of it by doing it alone.
And most of the time, they cannot distinguish that they're already in the addiction phase because they are in the denial stage.
You are not wrong, like when I was gambling, it stopped when it appeared to my family after losing a very huge amount belonging to my father, it was almost $3000. Before that time, I have lost large amount of money more than $10000. Though no family help but j know that it is high time I stopped for it not to affect my life because nothing good is coming out of the addiction. The best part will be to let people know, you family and friends so they can help you, especially family has a big role to play in this.
Yes, they can help you out and it's going to make you feel guilty when you're gambling not with your own money. And that's why you'll do the repetition that you must acquire it back when you've lost a big amount already and then if you've lost again, you have no choice but to get it back again and use the money of anyone where you're getting money until you realize that you're doing it wrong and it's not doing anything good to you anymore.
