Hi Joe, well done on looking for help.
Amounts are all relative really and not relevant to the addiction. other than it’s generally the finances which bring us to the point of seeking help.
You need to tell your parents. The important thing though is to not just tell them about the problem, tell them what you are going to do to address the problem.
I don’t just mean about how you will work the summer to pay them back, I mean what you are going to do to address your gambling addiction.
You have stopped before and gone back to it – what can you do differently this time? It is important not to try and do this on our own. there is a lot of support around these days – here and other sites, places like Gamblers Anonymous, counselling and more.
What barriers and accountability can you put in to make placing your next bet more difficult?
If you don’t find the games interesting without betting on them then don’t watch them. What else can you do to fill your gamble free time?
Maybe show your parents this site as well – they will find the Friends and Family Forum useful.
Keep posting and let us know what positive actions you are going to take.
