These are some ideas that come to mind where one can find help.

The story about the girl is definitely unsettling. I hope that nobody finds themselves in such a situation and if they do that they would be brave enough to ask for help. As for getting help, I'm not sure if it's enough to just subscribe to one of these services. The first step must be accepting your addiction and be willing to stay away from gambling. Still, not being able to access gambling sites is probably helpful to some extent.

I hope these links will help someone who needs support. Don't give up!
