Hey Harry well done on seeking help on here, this is a positive first step.
Now the first thing you should know is that you’ll get a lot of wonderful advice and support from this board from people who are recovering or are in a similar boat to yourself. But rest assured this is a battle only YOU can control. It will be one of the toughest battles of your life, and likely also the most important. Losing a large amount at a young age and over a short amount of time changes the way your brain is wired, the addiction will be with you for life, it’s a matter of whether you can control it or now. Right now you may feel 100% confident that you will reset and just give up gambling but no one simply says “I quit” and gives up forever magically. You need to WANT to stop forever, not to stop losing. You must accept your defeat and accept the losses are gone. You must also put in multiple measures in place that will prevent you from further gambling – full self-exclusion as well as gambling blockers on your devices if you play on the internet. It is also highly recommended for you to get emotional support during this process. GA is a great place to start although it is not necessarily for everyone. If you have anyone you can confide to please do so. Don’t do this alone. You are still young and sound like a smart individual with a lot of potential so please don’t throw away your future to gambling. You have time to turn it around and lead a good life but you must WANT to stop yourself. If you continue you will lose a lot more than your money (I’m sure you already know this). A life of gambling is a life of torture and you need to do everything in your powers to not continue going down that dark, dark path. Grieve the loss but never lose sight of the value of your life itself. I wish you the best of luck.
