I am writing to apologize for my behavior the other day. I know that I showed fury and it was wrong of me to do so. I understand that my actions were inappropriate and I regret it deeply.
I want to explain why I reacted the way I did. I was feeling overwhelmed and stressed out, and when you said what you did, it was like the last straw. I know that doesn't excuse my behavior, but I hope it helps you understand why I reacted the way I did.
I know that I should have taken a step back and taken a few deep breaths before responding. I should have been more mindful of how I was feeling and how my words and actions were affecting you. I am truly sorry for my behavior and I apologize for any hurt or distress I may have caused you.
I want you to know that I respect you and value our friendship. I understand that my actions were wrong and I am willing to do whatever it takes to make things right. I am committed to making sure this doesn't happen again.
I hope you can forgive me and that we can move forward. I promise to be more mindful of my words and actions in the future.
