Let go of your anger in any way you can, that does not involve your kids or your ex. And rebuild your best life by focusing on your actions and words. Move forward towards the hope that your kids will be healthy and undamaged by the divorce.
By allowing you to experience and process your own distress, without my interference, I am giving you the utmost respect. I am viewing you as whole, strong, and capable. And in my affirmation of you and your inherent ability to be strong and sufficient, I am reaffirming my belief in you.
