Hi Lewsi,
Welcome to the forum, well done on taking a positive step, and glad to hear that writing it down feels like a weight off your shoulder.
You are not alone, like you, I have been gambling for many many years which escalated into a real problem before eventually looking for support to help with it.
For next steps, and to continue moving in the right direction, I would recommend attending one of the New Members Practical Advice groups, that are held on Mondays and Thursday. There you can get some excellent advice, and tips on what you can do immediately to help with the problem.
I plan to attend the one tonight that is on at 19:00(UK), hopefully, I will see you there.
