Goodbye?

I may have said goodbye to my grandma for the last time today.  For several years now, she has been sick with a constant cough/flu sickness.  It has restricted her to her bed and she has barely enough energy to talk to us when we do come over.  This Thursday, she is going to Texas to see if she can get approved for a lung transplant without the addition of a blood transfusion (Due to her religion, she won't accept blood).  This doctor is the only one in the USA who agreed to do it without the blood.  If she does survive the operation/aftermath, I won't see her for 1-2 years depending on how fast she recuperates.
