I had a thought...maybe it doesnt fit, but maybe. Do you (as I do) ever get a "rush" feeling from the dramatics of a situation? Even if it is a difficult, painful situation, like your divorce. When it is over, and I am left with myself, I feel suicidal and depressed. No more drama, even if the drama was horrible, and no more "rush" and desperation. Its a sort of crash back to daily life and how to move on and cope with the daily rountine.
Your daughter sounds adorable. That is such a cute, adorable age with girls. She sounds like a little doll. And you are taking the best care of her. And making sure she doesnt see your very lowest moods is a very responsible thing to do. My kids have seen me in terrible moods and I regret that You are an amazing, giving and loving mother. I mean that. I hope you can give yourself the same loving care you are giving your sweet daughter

And if you ever figure out a way to get her to clean up her room....please post...Im still working on THAT one!
