I don't know of anything specifically for gambling, but maybe check out this site:

www.12steps.org

Maybe it could help, or you could email someone. There's also a chatroom there. I also just found this page by searching for gamblers anonymous online:

http://www.soberrecovery.com/

There's a bunch of forums there from the looks of it, all about recovery.

Also, just about anyone who has worked the steps for some sort of addiction can help you work the steps on this. Best of luck to ya!
