Freebird..you said it yourself. You didn't manage to quit because you didn't want to, despite all the consequences. Same for me. It's a different feeling, waking up and knowing you WANT to quit, it makes all the difference. That kind of mental approach will help you with the work you have ahead, as well as dealing with the cr*p that you will have to deal with to get this all straight. You can do this.
I wish you luck and strength in your new journey.
