It takes what it takes for all of us to get to the place that we need to be. You keep on relapsing because you keep on believing the lie; That this time, everything will be OK. But it never is is it? We have to learn to play the scene forward.
You might feel some relief for a while but sooner or later you will be right back where you started, carrying around more shame realizing that you accomplished absolutely nothing.
Do you have a sponsor who is taking you through the steps? Traditionally everybody seems to get into steps 1, 2 and 3 but they take their good old time with step 4 and most of the time they end up relapsing. I always tell people to put as much effort into getting through the steps as you would into getting drunk every day.
A life of sobriety pays off very well but you have to start out from the beginning just like everyone else and you have to actually stay sober.
