Welcome to SR.
I too became a bar hound, and did the movie thing alone, would wake up with the tellie on and not remember what I was watching. Life lost it's appeal, and existence was only tolerable when intoxicated.
You've started a new journey and found a new place to share your journey, and receive support, so stick around, read and post often and bear in mind that we've all been there, so you're not alone. It does get better if we work for it.
