I think the worst thing you can do is let yourself be eaten up by shame. Shame feeds the Beast.
I've been doing my grief work, trying to integrate my shadow side. It's been hard, very painful. But it's working, that gross tight ball of anxiety that I've been carrying in my chest since childhood is finally easing up.
This is the book I'm using, if you're interested, Home Coming by John Bradshaw. He was a recovered alcoholic himself. Although, I don't recommend you doing the work right now... wait until you are on more stable ground with more sober time.
I love AVRT. I think it is hands down, the BEST tool for quitting drinking. However, Jack Trimpey himself says that it's not for the emotional stuff, and many of us alkies have emotional stuff to work out.
Just take life as it comes for now, go easy on yourself. Try to manage the internal dialogue so you talk nice to yourself.
