Mens i saw your story about your gambling addiction and was shocked. Simply no words. You need to seek help asap, gambling problems is no joke. I know a nepali gambler by the name of IJustWantThisCurseToEnd and he considered suicide because was losing all bets (here is video about him: youtu.be/nqlYYJKlO-w ).
I noticed you live in UK, i strongly recommend going to your nearest mosque and confess to your imam of your sins, only through allah you can cure this filthy disease
