If you really want you can simply stop with it, most of the times its just in year head that you are addicted and you just need to focus yourself on not doing it.
What people say about help from others is also true by the way.
Correct. You are the primary person to help and decide for yourself. But there are really other people out there who got really addicted to gambling and even they themselves hate their selves a lot and cannot control their craving to gambling. But it all goes to common denominator - it is you that will going to decide as to whether or not you are going to quit gambling!
