I'm so sorry I have "barely" been here. With Jan needing transportation and doing extra errands I cannot be communicating to the extent that I owe it to you, my colleagues and friends.
you don't owe us anything but to take care of yourself and Jan. 
sorry you are so busy!
Skip, as long as you can check in and let us know how you’re doing, that’s all we need from you so that we don’t worry.
You’ve got to take care of Jan. We understand that she comes first.
hope she is doing well
It's ok. She needs you.Take care of her and you.
You need to take care of your wife. I don't see how you owe anything to any of us
take care of you and Jan - that's top priority
We'll be here when things settle down for you.

No need to be sorry, Skip. We understand. I hope you take care of you too. 
We love you anyway!
Jan comes first, we can wait
