I finally decided I didn't want to die. I quit, and I went to AA, got real with my therapist, got a baseline for my very sick body, changed habits, only allowed positive and supportive people in my life, and everything possible that kept me going further away from a drink rather than return to it.
I believe a "bottom" is internal. It only gets lower, til it's death. Our choice to stop, then work, then find a new way of living that is normal and beautiful.
