I was a very high 'functioning' alcoholic for many years. I had a good job, I was a mother, I was an auxiliary cop, I was a dedicated martial artist. But it was precisely this notion of 'still having it together' that prevented me from taking my issues with alcohol as seriously as I should have. I could've gotten sober 10+ years ago and saved myself a lot of heartache over the years.
