when you're addicted to gambling, it will be really hard to find another hobby because you will keep thiking about gambling
thing you can do, is to talk to others about your problem, like family or close friends, once they'll know about your problem, i'm sure that they will help
Nothing is too hard or too easy. I have 8x(not going to tell you the last digit) years old grandpa, and he is a smoker since he was young. We asked him to stop smoking because his doctor told him that he should stop smoking if he wants to live longer, and he immediately "stopped", but he is still secretly smoking somewhere around the house (for some personal reason he wouldn't tell). A few months later, he completely stops smoking. What I'm trying to say is, no one can help you if you can't help yourself.
