Hi Pete,
Well done on looking for help.
That conversation with your parents is important. It’s always going to be a difficulat conversation but what can amke it easier is not just to presnt the problem to them. Now you can also show them what youa re going to DO to deal with the situation.
You can show them this site, you can get a blocker for yoru PC so you can’t gamble on line, I expect your parents would be delighted to set any password for you.
When i stopped gambling there was no reason at all for my family to believe a word i said. They took notice of my actions thouhg.
