I went thru that with my mom when she was in the hospital. She would ask nurses and doctors to let her die. And occasionally she would ask me to "let her go". I reacted by not answering her directly, but giving her a hug and telling her how much I loved her. It seemed to settle her. I would just hold her hand and not talk. It is very disconcerting to hear things like that from your own parent. But, try to understand the context. I was sure there were days my mother really wanted to pass, but then other days when she was happy to see another day. It is stressful. Hang in there Haennie. (((HUGS)))
