Dear [Name],
I am writing to you to express my sincerest apologies for my recent behavior. I am deeply ashamed of my words and actions and regret my conduct.
I understand that my comments were insensitive and hurtful and that I have caused you pain and distress. It was wrong of me to say what I did and I am truly sorry.
I am aware that my words were unacceptable and that I should have been more mindful of your feelings. I understand that my words were inappropriate and I should have kept them to myself.
I am sorry for the pain and suffering I have caused you. I want to make it clear that I do not condone or support the views I expressed. I take full responsibility for my actions and I am sorry for any distress or discomfort I have caused.
I am committed to making amends and I am willing to take whatever steps are necessary to ensure that this never happens again. I am also willing to do whatever it takes to make up for my mistake and to repair the damage I have caused.
Once again, I am deeply sorry for my words and actions and I apologize from the bottom of my heart. I hope that you can find it in your heart to forgive me.
Sincerely,
[Your Name]
