My grandma is not suffering from dementia or Alzheimer’s and is pretty clear in mind. When any of us (grand children) or my dad are around she is very sweet, but also has outbursts of needing our help with very small tasks that she can do on her own. My mom has shared with me that my grandma is verbally abusive to my mom when no one is around and accuses her of abusing her and not caring about her. She also takes any chance she can to bad mouth my mom to other people. How do I help support my mom and care for her so that she is not running herself mentally and physically into the ground caring for my grandma?
