Oh Abba, my heart is breaking for you. I have been where you are and there can be no comfort, nothing any of can say or do. It stinks. It's the worst thing life can hand us, and it's so unfair.
And the worst part of it is that the only thing you can do for your grandma is to sit by her bedside and smile at her, even though your heart is breaking. She needs to see your smile and feel your warmth and hear you say you love her, even though she knows you do and she knows you're sad and scared, she needs to see you smile.
So forgive this silly old Judy queen if I offer you this version of Judy Garland singing Charlie Chaplin's song "Smile." This clip always makes me cry. I hope you will watch it and feel it and lose it and live with the sadness, cry your eyes out, curse, moan, weep, wail, and then, when the song is over, take a deep breath, let it go, go back to your grandma, and do the only thing you CAN do in the face of everything, which is smile.
