Sean - you have not failed. You only FAIL if you stop trying.... You are not in denial with regards to having a drinking problem, and that's a BIG thing...
You need to get a plan for sobriety, I strongly suggest you get out to AA and meet some people around your age that also want to get and stay sober.. Please keep going to different meetings until you find one you can see yourself attending more often, that's what I had to do...
You should also decide who your "friends" are vs. "drinking buddies"... No doubt in my mind that one needs to avoid people,places,situations for the first 60-90 days which typically resulted in having drinkings.....
