Lord, at the height my anger, I wrote very unpleasant things about a person

Lord, at the height my anger, I wrote very unpleasant things about a person whom I suspected has an affair with my nephew-in-law. Now, I feel sorry. Please calm down the people that I offended and I pray to you to please persuade them that they will not sue me for my mistake. I promise to control myself and never do such again. Lord help me to be more discerning before I make any action. Please protect me from any harm. Thank you.
