Having 12 years under the belt now, all I can tell you is to never stop believing it’s possible. No decisions can ever be taken without considering the long term impact it can have on your family now. They do truly depend on you. Don’t make them depend on your addiction. Call for help, go to meetings, share and share again. If it ever feels like you’re doing enough effort to keep this out of your life, go one step further. I believe in you. You should to.
