Well, one of the symptoms of addiction is denial, so it should come to no surprise that you can't accept it.
Acceptance will come. In my case it came in the wake of the struggles I had to quit. Folks without addictions should be able to quit when they decide they need to. I couldn't.
I can also tell you I gained a lot more insight to my problem at about 30 days sober, which gave me the distance to be objective about my problem. With that came acceptance and the knowledge that I could never drink again.
Good luck to you.
