Are there NA meetings near you?
I have friends with multiple addictions and they find NA to be more useful to them than AA. Narcotic addiction has some unique challenges, and AA doesn't like to talk about substances other than alcohol...which I find kind of an anachronism in the modern world, where so many addicts have multiple substances. NA, CA and CMA all welcome working through all addictions, and they're all 12 Step.
One of my rehab friends does both. She was an actual Nurse Jackie, as she got caught stealing from the narco cabinet at work and is in the nursing recovery program. They required her to do both fellowships as a condition for licensing, as she was also an alcoholic.
You're probably going to find people at NA meetings that are facing the same challenges that you describe above.
