Hi Steven! I'm sorry you have been going through this. You are right that your bipolar probably play a huge part in your substance abuse. Are you seeing a doctor and on meds for that right now?
I've never really been addicted to pills, but alcohol and whatever else I can get my hands on, (coke, e), I am for sure. I've only been sober for 8 days, and it's been pretty hard watching people around me still party, but one thing for sure is I feel a lot better.
I too feel very alone in what I'm going through, but this site is awesome and the people here are wonderful!! Stick with us, because you and I are far from being alone in this.
