“Life is not orderly. No matter how we try to make it so, right in the middle of it lose a leg, fall in love, drop a jar of applesauce.” - Natalie Goldberg
I'll repeat what everyone's said, I'm so incredibly sorry for your loss. Hopefully you can just take it one step at a time & delegate things as necessary.
You've been a good care-taker, now it's time to take care of you. ((hugs)) my heart goes out to you and your family.
