@buggirl55 I really understand your wish and need to stay with your mother in her last minutes. I faced just such a situation last summer when my mother was dying. Almost at the end, i had to leave because of my health at the time. I had to take a long flight, alone, through 2 busy airports. I new that I couldn’t wait. My sisters were there and they would use FaceTime to call me so I was able to say goodbye. Clearly, it was difficult.
Also, in my experience as a nurse with cancer patients, many, many patients choose the moment they will die. Frequently, death happens when family is out of the room. I’m telling you this so you won’t be hard on yourself if you need to leave the room.
I know that this is a difficult time for you and your sister, so I’ll be thinking of you.
