That's for the rest of us mortals. For people who have an addictive personality like the OP have to give up gambling altogether. It's like alcoholics. When they quit, it's for life, not a drop more because a single shot restarts a self-destructive pattern that usually takes a long time to stop again.

OP, what you need to do is 0 drugs and 0 gambling. For life. Get used to the idea. And get help. If you have to tell your parents, friends or family do it. It's easier here because you are behind a nick but find someone IRL to tell. And if you can find an addiction treatment specialist, do it, ASAP.
