Creative Writing: Life-Changing News

My sister has been my biggest supporter. She comes in to see me every day, telling me to stay positive and that a donor will come through soon enough. She seems pretty sure of it, too. But she has always been the optimistic one.
She hasnโt come in yet today, though. Seems odd for her, but I guess it could all start getting to be too much for her to handle.
โGood news, Mrs. James. We have received a heart from someone with your blood type! Youโre scheduled for the surgery in just a couple of hours.โ
Well isnโt that wonderful! Even though I had accepted the fact that I was going to die in that hospital bed surrounded by those four white painted walls, I was finally saved. My sister would be so happy.
I went into the surgery room wishing she was with me, but everything was happening so fast and there was no time to waste. I was sure Iโd see her afterward, anyway.
โWhere is my sister? Why isnโt she here? I need to call her.โ
โShe wonโt be able to answer, Mrs. James,โ the doctor said. โShe now rests within you.โ
