I am glad you are here Star. I was on pills too. Lots of pills. My first DOC was pain pills then it changed to benzos (xanax). I have been clean and sober 8 months and life has gotten really good for me.
It is great that you had 3 years. You did not lose that. You still have the experience of it.
I think it is great that you are going to go to NA. I go to AA and have a sponsor and work the steps. it is a really cool way to live.
Keep hanging out here, you will find awesome people here and keep posting!
