For me, admitting to myself that I had a problem was THE turning point in my life. Once I had done that, the rest of the work I needed to do did not seem so daunting.
I think you are right on about denial as it is one of an addicts most powerful tools to justify continuing to drink or use. I was in denial that my severe gout attacks were being caused by my beer consumption. Since I stopped drinking, I have not had another attack....
I'd suggest that you attend a meeting EVERY day for a while. Look for the similarities and dismiss the differences you hear in the stories of others. Read the first 162 pages of the book of Alcoholics Anonymous and get in touch with your higher power, no matter what that is.
Glad you are here!
Good Luck!
