Addiction is so weird as it affects each person differently. My dad quit when the doc told him quit or die. With 7 kids he chose us over himself. On the other hand my mother's friend willingly died from alcoholism. She didn't want to stop. Never tried. Mom said because it was more than what she could deal with in her head and body. Perhaps it comes down to motivation? I don't know, however watching Marie die a horrible death and my dad conquer smoking for us kids, I am thankful for their suffering as I have learned and benefitted from it.
10 months sober is fantastic. You are positively affecting someone else out there, and you may be surprised at who it is. We are proud of you!
