The reasons for drinking are not really reasons. They are bullet-points to continue down the same path.
The only way to heal the body, mind and psyche is to stop drinking first, then sort out the rest. We all have a "the rest" - but there is no trauma or past situation that is worth committing a slow suicide by alcohol. I know I couldn't really sort out much of anything until I had been sober a couple months. It took that long for me to figure out which way was up.
