My Mother Passed Last March Of Metastatic Pancreatic Cancer And

My mother passed last march of metastatic pancreatic cancer and now my grandmother is battling the same disease. My Grandmother is starting to vomit bile and her eyes are very jaundiced. How long do you think I have with her. I only ask this because I am a med/surg nurse and I know that her body is shutting down but I just want a little reassurance. My mother was diagnosed with the same cancer EXACTLY 360 days earlier than my grandmother and she died in March. Before she passed she was vomiting green bile as well.
