Somewhere along the road of life, we come upon people who are driving smack into a dead end. You can try putting up Stop signs, you can put up a brick wall, you can put safety messages on their radio ... but they've made a decision and you can lead a horse to water, but you can't make him drink. I'm very sorry to hear about your mother's condition. Some people react to bad news by trying to turn things around. Some people react by doing more of it so the suffering will end quicker. Some people keep doing it because they're just in denial, as they believe themselves immortal. Her decisions suck, but you're now in the unenviable position of planning ahead since she's obviously not in the mood to act like an adult. Maybe acting like her funeral's tomorrow might snap her to attention. You never know. If she realizes you're coming to grips with her demise, she might realize it's on her list of things to do. Of course, reverse psychology may not work -- but at least you'll be better prepared for when the day really comes.
