My 90 year old Gran  has been complaining on and off for a year about pain in her stomach but both the GP and the walk in centre told her it was constipation. The past few weeks she has been really unwell and lost a lot of weight. She was admitted to hospital a week ago after she fell in her flat. The hospital have done some tests and are convinced that she has bowel cancer which has possibly spread to her other organs as she has deteriorated massively in the past few days. 

As she is so frail, the doctors have advised that they cannot treat her but put her on palliative care. It's horrible to see her suffering the way she is but I'm so scared of her dying too. Is there any way of knowing when she is coming to the end because as much as I am terrified, I want to be with her when it happens.
