Doing a short sale on my home and mom with dementia keeps rehashing the situation. It's getting me down. Suggestions?

Sapphire56, first of all I'm sorry about your mom's mental deteriorating state, what an awful thing to lose your brain isn't it? Secondly, I am so glad you have sisters who are willing to bear the burden with you. I guess it's time to take control of the situation. I realize your mom thinks she's still able to make these decisions herself, but the fact is she can't. If I were in your shoes, I'd start just talking about her move out of the house as matter of fact. No more arguing about it, or stressing her constant talking about how she can take care of herself, just make it a fact that she's moving to be with your sisters. No more arguing, talk to her in a positive hopeful way that she'll be embarking on a new experience that will benefit everyone, and how happy her other daughters will be. Also, lay the blame on her not being able to live independently at her doctors feet, they don't care. My mother-in-law has dementia/alz and it takes my talking about something A LOT that finally gets her brain to consider it 'old information' so she can remember it and then process that information. That's why it should be YOU talking about her move out of the house and to your sisters area, and how wonderful that will be. Good luck, I know it's hard. Take control.
