Ann,
I don't even know her but I admire your mother. What a lucky person you are to have a mother like her.
From your messages, my guess is that she is handling the last part of her life with all of the grace and dignity that she knows how. My guess is that she likely lived her life that way before as well and this is no great surprise to you that she is baffling the hospice folks with her fortitude and attitude.
If they say she is in end stages, then I would have to just believe it. If the bleeding is coming from the kidneys, then it is likely that the cancer has spread there.
While I am sorry for your loss, I am happy that you had a woman such as her to raise you and guide you through life.
Give thanks for the time you have had together and spend as much time with her now. A woman such as her should not die alone without having the comforting hand of family.
When my mother died at the age of 47 from breast cancer, I did not sleep for 5 days and I held her hand the whole time (except for bathroom breaks). I just couldn't let her be alone at the time of her death after all she had done for me and our family. Somehow, after she had lost all communication (even the just hand squeeze communication we worked out) I knew it was time and called my father who had gone home for some much needed rest. He came to her bedside, kissed her the forehead and told her he loved her and goodbye. That was the exact moment of her last breath....
That was a lot of years ago and I have to admit that my eyes were already tearing up while I was typing the part about the grace and dignity of your mother and it was darn near impossible to see through the tears in my eyes when relating the memory of my own mother's death.
I wish you, your wonderful mother, and all of her friends and family peace and comfort during this time.
Mike
