Pretty much all NA areas have a phoneline. You can get a ride to your first meeting, and there you can find some people with some clean time to give you rides to others.
Honestly, if you can get to the local ones, you can find rides to others as well. I got rides for my first two years to meetings I couldn't walk to and went every day.
I can tell you that there is no magic cure for being dope-sick, but you only have to do it once.
I used painkillers for a good long time myself, the last 8 years were all day every day.
Life is a lot different now.
Give yourself a break. Ask for help, and put in the effort. It's worth it, and so are you.
