While the situation itself is terrible, please cherish the opportunity to tell her goodbye. Make sure you tell her everything you want to tell her, i.e., "I love you," if you are comfortable saying that. As Catty1 said, the hearing is the last to go. I didn't get a chance to say goodbye to my grandma. She was already gone by the time I got there. I just hope she knows that now.

Hugs and prayers to you, your grandmother and your family.
