Hi edhavana,
Sorry to hear that you have slipped and went back to gambling after a few months.
Charles asked some great questions back in December last year after a similar slip that seem just as relevant to this recent slip.
If you lost 15k in 3 days, it sounds like you have easy, fast, unaccountable access to funds. How can you make yourself accountable? What barriers are you going to put in place? What extra support are you going to connect with?
Answering these questions will be very important to reduce the chances of being able to stay gamble-free. If you give them some though, and provide your answers here, the community can provide feedback and advice on any additional steps you could take based on their own experiences.
