Many times there are some other levels of addictions that the addict will have to change his environment since the majority of addicts in gambling are due to easy access to casino houses.
If you don't have the strong will, you won't be able to come out of it. Many people like professionals can give you directions, medications, alternative ways of avoiding that addiction but in the end it all comes down to you. If you don't decide it on your own, no one else can help you.
Realization is the key but in order to unlock it you need self-willingness to do it in the first place.
Which is valid, even if you realize that you are doing things the wrong way, but you are not willing to adjust. There's nothing that can be done, and even how helpful the people that surround you without your own determination to quit or to stop, then there's nothing that can be accomplished, it's you that need to take actions plus the help that you are going to receive, that are the things that you can use to quit away from anything that relates to addiction that you have, without it then you are going to keep doing things that will endanger your financial and mental stability.
Responsible gambling means that you are in control of everything, having that right attitude and mindset to make sure that you can limit yourself and be able to direct yourself in that right direction that you need to do.
