Horrible situation WM, thinking of you and sending loads of vibes.
I know exactly how you feel with the distance and the inability to "be there" for your child.
She is in medical care, kidney stuff is fairly well known, but hard to trust that they will get her recovered.
All the normal advice goes out of the window, you can't avoid the worry and won't rest until she is on the path to recovery.
Hang tough and know we're thinking of you and wishing for the best speedy recovery.
