Dear [Name],
I am writing to apologize for my faulty judgement. I understand that this has caused you a great deal of frustration and inconvenience, and I am truly sorry for that.
I want to start by saying that I take full responsibility for my actions. I should have taken more time to consider the situation and think through the consequences of my decisions. Instead, I acted impulsively and without considering the potential consequences.
I understand that my actions have caused you a great deal of stress and worry. I can only imagine how difficult this situation has been for you. I can assure you that I have learned from this experience and I will be more mindful of my decisions in the future.
I am sorry for any disruption this has caused to your life. I know that you have put a lot of effort into your work and I regret that my actions have caused you to have to put in extra time and effort to make up for my mistakes.
I am sorry for any embarrassment or discomfort my actions may have caused you. I understand that this is not the kind of behaviour that you expect from me, and I will do my best to ensure that this does not happen again in the future.
I understand that an apology is not enough to make up for the damage that has been done. I am willing to do whatever it takes to make this right. Please let me know what I can do to help.
Once again, I apologize for my faulty judgement and the consequences that it has caused. I hope that you can forgive me and that you can trust me again in the future.
Sincerely,
[Your Name]
