Do you take her disorder into consideration when she is doing something “bad”.
I only ask because that may be causing her resentment for you if she cannot help it.
At nine it is a possibility that her hormones are all over the place with puberty nearing, which typically make symptoms of ADHD more severe. Unfortunately one of those symptoms are mood swings.
I wish I could suggest ways to avoid conflict with her but I don’t have that answer. Just keep supporting her emotionally to the best of your abilities. I wish you the best of luck!
