Oh boy. It's tough when these problems start. Too bad your grandma isn't closer.
You don't put your work before family that I've ever seen. Your work and family life are linked so closely anyway. You can't go if there is bad weather. The honest truth is there is nothing you can do for your grandma that isn't already being done, and your kids need their mom, so not worth any risk. Your dad is the one who will have a hard time (it's his mom

), but you can support him over the phone for now. I think granny already said it, but this is going to be a long haul with Donnie and a broken hip... months of healing. She's normally in a care facility? Do they have skilled nursing? After the surgery, she will probably need to go to a skilled nursing place. She will not be walking for awhile, and will need physical therapy in a month or so.
