block your internet 
That will help for people sometimes but not always, because see it is like you leave the college because you do not like a teacher. You have to cure the disease friend, stop using internet also means you can not earn anything then. Better block gambling sites. But that too not effective in my own experience. yeah, or look for an emotional support from your family and friends.
You actually don't need a professional to get out of gambling, try to do some productive works.
get out for a dinner, or travel.
those things will actually help you a lot.
