I found Al-Anon to be a great start on my journey but it is one of many tools I use to work on myself. Sometimes I go to meetings and leave even more depressed than when I started...sometimes I get really, really mad at God while I am there. Sometimes someone says exactly what I need to hear that day and I walk away feeling elated.
I have tapered off lately because I found myself dwelling too much on my situation while attending Al-Anon. I do work the steps a little on my own, when I need a reminder.
