Ken, my heart just breaks for you. My sister went through the same thing. She got to the point that she just never wanted to do anything. She regretted that at the end. I don't know if you are going to die or not..it is up to God, but I know that my sister died last month, and she seemed almost happy at the end. Her last words to my Dad were.."I love you Dad, but I have to leave now. She smiled and didn't say anything else. She died a few hours later. She was no saint, but she did believe in God and she knew she was going to a better place. I have had dreams of her since she died, and in all the dreams she was comforting me and she was really happy.
I hope you can find peace somehow.
Love,
Bobby
