This is a very difficult period, I know, because I experienced it with my father. Be ready because anything could happen, especially if your father is with his estranged wife. If their relationship is still poor, it will be even more difficult for your father.
It was on a Wednesday that they put my father in Hospice. He was so depressed. I had all I could do not to break out into tears in front of him. He looked so helpless. I remember three days later, in the morning, my mother calls me, and tells me I needed to come quick. When I got there, they had already given him the morphine and my mother said my father asked her to continue to give it to him because he no longer wanted to live. He was barely conscious. And for the next 6-7 hours, he would briefly open his every so often and look around. I don't remember exactly how we knew he was going to pass, but just before he did, he opened his eyes, raised his head and looked around at us as we were all standing around the bed, my family and a couple of his friends, and then he lowered his head and we heard the sounds a body makes when it shuts down. I put my fingers on his pulse and felt it gradually slip away.
