Tired and Emotional

Been awake since 2am churning things over and did a full day at work.
Emotions all over the place as I process my eldest sister having had an above knee amputation. How she has remained so positive and sending jokey messages I really don't know. 
Visiting her again on Saturday, train strikes permitting.
I just want the best care for her and for her to be able to live safely and comfortably .... One day after a time.
