Hi bluesky76,
Welcome to the forum and well done on admitting the problem and taking a positive step.
It sounds like your easy access to both unaccountable money, and options for gambling are the building blocks of your problem. These 2 areas can be addressed which can be a big start and certainly was useful when I first started trying to stop gambling. To start with you can 1) Put as many barriers in place as possible to make it difficult to gamble for example contacting all local casinos, and requesting that you are given a lifetime ban, closing online accounts, software blockers for electronic devices etx and 2) Have someone else you trust manage finances for a while, In this scenario, you still maintain control over your money, and decide where it is spent, but any spending would have to go through this person first.
I also strongly recommended the new members groups Dunc mentioned held on a Monday and Thursday, here you can speak with Charles who can provide further advice and recommendations.
