Hi Steph and welcome to the site. Well done on looking for help.
As others have said, barriers help, particularly in the early days. If you get a blocker for your phone/computer it’ll stop you finding anotehr site. Financial accountability will also help.
The good news is that you know you can stop, the difference this time is that in 1 or two months time you will be using support, posting here and getting to the groups. Maybe getting to Gamblers Anonymous meetings. We all find support when we want to stop – the trick is to keep using it to maintain recovery.
Keep posting and let us know what positive steps you are taking and how you are filling your gamble free time.
