It seems my grandma is near the end. The final decline was surprising in its totality. Last Thursday night, she was talking, watching TV, fairly with-it. Within 12 hours she had entered a semi-comatic state and has been lingering ever since. We've been with her daily and I'm very grateful for the scant hours of lucidity she has given us. A lot of it has been babble that seems connected to her childhood ("Tell Mom I'm sorry, I didn't mean to make her angry!" and the like) but interspersed have been touching comments, always with a thin smile, like "Hi Michael, I love you."
This is the first time I've been around a dying relative. I just hope she passes on soon so that the ordeal is over, mostly for her sake but also for ours. It's beyond agonizing.
