Of course, relapses do not have to happen. For many people they do, but don't take it that everyone has to relapse. Good for you on Day 6!
I also wanted my family to understand what I was going through in early recovery. It was so important to me that they 'get it'. They didn't want to know. Yes, they wanted me to get better, but they had no interest in what I was going through. Learning to respect their feelings was a big step for me.
