I Have Abused Pain Pills

I recently won my battle with cancer but I've been on pain pills, nerve pills, muscle relaxers, medical cannabis, basically whatever you can think of for years now.
I'm glad i'm cancer free but now I don't have a reason to justify the prescriptions. I have no idea how to live sober, and it really scares me. I've been the sick girl with the home pharmacy for so long that it's Like it's part of my identity. I don't want to be that person but I don't know if I want to say good bye either.
