My mother is 92 and has vascular dementia. Let me explain that my mother was always an angry, vindictive person to her children. Her visits usually ended with her getting mad because we wouldn't do something she wanted so she just packed up and left without a word. I am caring for her in my home now. She has extremely bad paranoia and thinks I am stealing from her and hiding her things. She will scream, yell and cuss me out several times a day. What am I supposed to do? At wits end. Thank you.
