You say I know it is going to be hell.
Yes stopping isn’t easy, especially if you are doing this every day – but it is possible. I am around 10 years without gambling, someone else recently celebrated 16 years.
I only really stopped when I made a decision to treat my recovery as seriously as I treated my gambling. In other words every day I lived and breathed “not gambling” and doing things that would help with that.
Banning yourself is a great first step – but if you have the means to gamble then you will. So cut of the means. Talk to your wife about her handling your finances for a time until you feel strong enough to take them back. No access to money – no betting. Also see if she will take part in this site as well. Read or post on the families and friends part of the site or speak to someone in the facilitated groups. The more insight she gets into your problem the more she can help and also get support for herself going through this.
Also get great support for yourself. See if there are any self-help groups like GA in your area or talk to someone about counseling. I was struck by, “I felt empty without the noises and the rush, but I feel empty with the noises and the rush as well.” So where is this emptiness coming from? Possibly talking to a counselor would help with this.
In the early days I would throw everything at your recovery and then you can lessen this once the urges become fewer and you begin to settle into your new non-gambling life. I wish you well.
