Hi Patriot, well done on looking for help.
The bad news is that you are not going to get 400 Euros in a week. The good news though is that you can stop gambloing. read the other stories here, you will see many similar to your own. You will alos read the success stories, what are they doing that you can apply to your own situation?
Before you get paid again have some barriers in place. Instead of giving your wages immediately to the bookies maybe give them immediately to your mum. It will still be your money of course, to spend and gradually pay off your debts, but accountability will mean you can’t gamble it secretly. keep posting and let us know how you are doing.
