You have to get some other hobbies that don't involve luck and money in the same action.

You can just watch some movies or join a gym and do some exercise, it's good for stress. Gambling addiction is a real problem, almost any alternative is better.
need to move out from that environment that always make you gamble again and again. To move out that you need some support from your family or relatives.
Yes we must change our surroundings so that we can avoid the emotions towards gambling. But mostly gamblers do not prefer changing anything just due to addictions. Changing our environment would definitely help us to stay away from gambling.
