I am truly just disgusted with myself and i know what i need to do but i can’t help it

i have a severe gambling addiction, like it’s really bad, i don’t make that much money overall and i have 3 kids but the money that i do make i basically use all of it to gambling and then am left having to doordash to make money throughout the week just to survive, i don’t understand why i do it, i keep telling myself to stop or just don’t do it, but it’s like an itch that i need to scratch, i know overall i’ll lose my money, but i have the hopes of “going on a run” or just hitting a mega jackpot, but i also feel like if i did hit a jackpot i would think i can do it again and that would be even worse for me, i know i have to STOP but i don’t know how to, i gamble on my phone, so i can’t not have my phone, and if i don’t gamble on my phone i’ll eventually end up at a casino in person, i know i need to stop and i know it’s as simple as just not doing it, and no im not gonna go to a place for this, i know i have an addiction but i don’t know how to stop it, i would like to stop but when i have money i think i can make more, and if i do make more i end up just losing it and chasing to get it back, i just don’t know what to do

tldr : i have a gambling addiction and i want to stop it but i don’t know how to…
