Welcome Thatslife - sounds like you have a bunch of time on your hands. I have recommended this book to a few others it was recommended to me form another SR member: In the Realm of Hungry Ghosts. Actually speaks volumes to heroin and why your brain developed the way it did. What we have in common with other addicts.
Good luck. Given your comment about your family ties, I am taking all meetings or therapy are out? If so, perhaps AVRT and Rational Recovery combined with online support might be useful. I personally am familiar with AA but am starting to learn more about other programs too.
