When I decided to become clean & sober I was warned VERY STERNLY that my disease would in some way, some how, put up distractions to keep me from focusing on MY recovery.
I took that warning very seriously.
When I found myself looking at others as a reason to either use OR as a reason to stay clean/sober, I QUICKLY shifted the focus back to myself.
I cannot now, nor could I ever, control the behavior of others. But my 'disease' constantly tries to tell me different.
I truly believe I have stayed clean & sober because (God willing, knock on wood) there is NO PERSON that can make me use again. and I stay clean/sober for ME first, everyone else (yes, they are important) second.
Good luck, best wishes, keep coming back.
