Congratulations.
No telling just how many readers may benefit from your hope filled story. Just think: if because of your well written story you succeed in bringing just one substance afflicted person around to freedom and happiness...
Or even if your telling gets a single troubled reader to promise him/ herself to: ' Damn, I think I can do it too?' Then you have potentially saved a life, perhaps more than one. Oh, and think of the lives around the troubled soul, renewed hope, the chance for new beginning, families preserved...
Be strong.
Blessings.
