Keep coming back Daphne, many of us did not hit that "low bottom" where we lost everything. Many of us did not lose all those things, but we did lose our self respect.
Your post brings back memories for me: when I first thought about quitting, I was only concerned about my physical health. I didn't understand that my mental health was in deep trouble.
The classic alcoholic? God knows if there is one. Alcoholics can be daily drinkers, or not. They can be bingers, or not. They can pass out, or not. They can lose their jobs, families houses, or maybe not.
But there is one thing we all have in common: we found our lives were unmanageble due to alcohol, that we were powerless in face of it.
If you have health problems due to alcohol, maybe it is an unmanageable aspect of your life.
