I know how you feel. My father passed on this day three years ago. My mom is having the same things happen to her as you are. The bad dreams and all that stuff. I know it is hard, but the only way to make it easier is to be strong. The way that I make myself feel better is to think that my father is in a better place. He is not suffering in pain and he is with his uncle drinking beers and hunting everyday. I was there when he passed and had to ask the doctors to stop recessitating him. That was the hardest thing to do. Its hard and time will feel that it is passing at the slowest rate. But it will get better over time. My prayers are with you my brother, and I hope things will be better in the future. God Bless
