Dear [Name],
I am writing this letter to apologize for my recent behavior and the irritation I caused you. I understand that my words and actions were wrong and I deeply regret them.
I want to take this opportunity to explain why I acted the way I did. I was feeling overwhelmed and stressed out due to a lot of personal issues that were going on in my life. I was feeling frustrated and I took it out on you, which was wrong of me. I should have taken a moment to step back and take a deep breath before I said anything.
I understand that my behavior was inappropriate and I want to apologize for any hurt or discomfort that I caused. I should have been more mindful of my words and actions and I am sorry for not doing so.
I hope that you can accept my apology and forgive me for my mistake. I promise that I will do my best to be more mindful of my words and actions in the future. I will also work on managing my stress and emotions better so that I don't take it out on other people.
Once again, I am sorry for my actions and I hope that you can accept my apology.
Sincerely,
[Your Name]
