Thank you for sharing your Al Anon experience, MattMathews. To be fair to the people in my group, I'm not sure how much of a chance I've given them to reach out. Plus, I live in a big city where the culture is generally very reserved.
It's my own issue and I really need to work on it somehow. It's been interesting to hear that other people replay conversations in their heads. I thought I was the only one who drives herself crazy by doing this!
