I lost my husband five years ago. We always drank, and as with most people, it became a ritual. When I lost him, I kept up the ritual (and others, too) because it made my unwanted new life feel normal. I also didn't give a monkey's about my health and really wanted to die, and still do, but less so. I hit an empty spot late morning which I fill with a gin/vermouth. Start again at around 5pm, sometimes earlier. You would never guess, as I never get drunk.
Tried AA once, and it was full of people wrecking their lives with alcohol, and I felt like a fake (hated it anyway.) Know I'm putting myself at risk of all kinds of nasties, but it's so hard to control. Alcohol also, in my mind, connects with creativity, so if I'm stuck (I'm in an overcrowded creative profession anyway), I drink, and convince myself it helps, which it sometimes does. Joined "Club Soda" on Facebook, which I sometimes visit because it can be helpful, and has none of AA's semi-religious style which I loathed.
I am also old-old, and dread the future, officially opting for euthanasia, but that's not easy.
