You are brave to start this journey. I'm glad you're here. I think you should most definitely consult with your doctor before anything else.
The one thing I remember that someone in AA told me at my first meeting (amid my buckets and buckets of tears) is this: there is a solution. And that's true for you too. I don't recall very much about what else she said - I was drunk and sobbing. But I will always remember that. There is a solution. And she turned out to be right.
It may not be easy at first. It may turn out to be the fight of your life. But you do not have to go through life addicted to pain pills. And it will get better as you go.
