I don’t know about US banking regulations, but in the UK the banks offer a service of blocking remote purchases from debit and credit cards. Maybe worth your while looking into this.
At the moment you sound determined to get your gambling problem sorted, and you’re right many of us have pledged at one time or another to post every day.
It’s great to have somewhere to seek support such as this site, but it is also worth your while, I would think, to seek out some live support, GA ( Gamblers anonymous), for instance. Personally I found counselling/therapy a massive help.
I had gambled from a young age 14/15ish I’m 51 now bit have managed to stop gambling. If it wasn’t for the fact I bought some lottery tickets this time last year, I’d be over a year without any sort of gambling whatsoever.
You’re a young man with most of your life in front of you. You’ve shown great tenacity in standing up for yourself against this addiction. Take this opportunity to get yourself sorted out because I promise you the life I’ve had because I didn’t take action against my addiction has been pretty pathetic and pitiful.
Good look with it.
