Dear my colleague
I hope you are doing well, I am writing to sincerely apologize for not being to help you with your project as I promised.
Unfortunately, I had to deal with unexpected family emergency last week. It took me most of my time and attention. It make me unable to assist you as I planed.
I feel really bad that i cannot assist you. Especially, i know that this project is important to you. I did not mean to cause you any trouble.
To make up for this, I am happy to review final draft project or help any remaining tasks this week. Please let me know how I can best support you moving forward.
Best regards,
Mina C.
