Dear Mr/Ms [Name],
I want to inform you that I will not be available for work from [day, date] to [day, date]. Since [Thursday], a very crucial matter of personal nature has presented itself in front of me.
I don’t feel comfortable revealing the details here [if you feel so, you can carry on with details], but I need some time to get it sorted out.

This family matter is making it impossible for me to pay attention to work. I hope that I will be able to resolve it in the given period. Till then, I will remain available for email and phone calls. Once again, my heartfelt apologies.

Sincerely,
[Name]
