my dad is in the hospital and is having surgery tomorrow. My mom has dementia and has been staying alone. She needs someone to be with her but is so much against anyone helping her that I am afraid of how she will react to a stranger being in their home not to mention when I tell her how expensive it is going to be. I am so alone in the decision making and really don't know what to do. If anything happens to her I will never forgive myself. What do I do?
