Not sure what to do anymore

So the last 2 months have been a complete 180 on my life, i had a cushion of money that i used to buy an engagement ring for my girlfriend, and growing up poor this was a huge deal for me, but alas growing up poor means i always tried to find a way to make money, after the military i was in a bad place and gambled alot, i stopped when i met my girlfriend and until i bought the ring, then i panicked because i didnt have money anymore so i relapsed. And it was terrible. I finally came clean but im now im debt and maxed out my cards, i cant pull a loan out because ive always had terrible credit and all my money goes to the debt, well i cant even pay for basic necessities anymore and im lost, hopeless even. My girlfriend is impatient about it because i say i am gonna pay this and boom a payday loam gets taken out and i cant anymore and this has been going on for 3 weeks even though i thought its stop by now. My car broke down last week and now i dont have a car. And it seems impossible to even get one step ahead without getting knocked down again. Ive lost hope and im not sure how to get out of this. I havent gambled in a month going to GA now. But everything bad that couldve happened has happened and now my girlfriend keeps asking wheres my money and i have to explain to her every week whats happening. I dont have a car anymore so i cant pick up gig work either. Im truly stuck. And shes getting restless. I dont wanna lose her but it is my own fault. I just wish i could climb up again without something ripping me down.
