Going On Break, want to give mass message

Hello,

I just started selling on Amazon, and unfortunately, I need to take a break due to outside circumstances calling my attention. Is there a way to tell all of my still pending orders all at once that I am taking a break due to outside forces? I don’t have many, and I figure that most will just get it from someone else, but is there a way to just put an alert for my store as a whole? I am just completely unable to send them the way things are now.

TLDR,

Is there a way to tell everyone who is buying from me that I can’t fulfill order due to family emergency in one big grand message?
