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.
thats true, but gambling used to be my only addiction to be honest and it was really hard to quit it
Any addiction is hard to quit, but once you have realized it that you have a problem you should look for professional help, the help of your family and keep a very clear focus of your goal, to quit gambling.
Whenever a person realize that he is addicted and he has a problem from there, he then be able to give away from there, it is true that he find it hard to give up from there but he try his best to stay away from what he feels the problem, but those who are unable to understand that he has a problem from a place/addiction are unable to give up from there and stay the whole life at there.
