Hi JayDee, well done on looking for help.
I hope you are reading some of the otehr threads here. You will have seen a lot of stories similar to your own. You will also have seen the success stories – what are they doing that you can apply to your own situation?
What barriers can you put in place? You have been honest wiht your mum and partner, now they can help you with accountability so that you can’t gamble secretly. Get yoruself excluded from your local/usual gamlbing establishments, get a blocker for your PC to stop online gambling.
Plan your gamble free time so that both your time and thoughts are filled with other things.
Most importantly use support. You haev this site, maybe check out your local GA mneetign as well. If we could do it on our own then none of us would be here.
Keep posting.
