Not entirely sure how your kit sales have escalated to threats against you & your family (which obviously isn't acceptable) but then I don't know who you've been dealing with, nor the tone of of messages between you & your buyers.
I will also agree that yes, life is more important & does get in the way of airsoft......
BUT
If you've got time to put sales threads up, give out your payment details & take the money, then you need to get the gear sent out in a prompt manner.
Edit: i should add that if "life", or more to the point, emergencies, do prevent you from getting stuff posted, you need to be 100% transparent about this & keep buyers in the loop.
