As said by others, gambling is not a sin but becomes a habit hard to get rid of. You need to get rid of balance and use slower internet connection. Ban all the gambling websites you use and use antivirus protection. Try to get another hobby. Good luck my friend. It takes 21 days to get rid of a habit. Keep it up and you sure will
The only thing that can help you in my opinion is finding another hobby because its way easier to do this and if you have some friends you first start to find a hobby with them..
I honestly think that is the best thing you can do these days.
