Without a self-will and without that determination to eliminate such feelings, it's not a need it's a bad desire that you don't need to fill each time that you think that you need to gamble.
For me it all starts there, willpower is the only thing that can make the difference, there is no other way, the help is there and it can be given, but if the person does not do their part nothing will be achieved, nowadays things are much more open, the information is there and well social networks help people distort their objectives, when there is someone with addiction you have to consider taking care of them in the smallest way because it does affect them.
A helping hand is needed once addiction already develop, a little gesture that you care will be big enough to help a gambler who's struggling to work on their own will, that's something that push them to keep trying, as long as there's someone who still believe in them that they can change it up and able to overcome the issue, that may serve as inspiration and will give them the will to force themselve to change up.
