She claims I locked her out of the house. Then the story expanded that I was looking at her thru the glass while she pounded on door. It never happened. My aging father asks "Why would she make it up"? Family members who care for her have not gotten her any psychological help and think it's normal for old people to get angry sometimes. But mom is completely fabricating a story and expanding on it. She is delusional about some things. My mom almost hit me when she wanted me to leave. She screams insults. Calls me names. Dad never defends me. Says he's trying to stay out of it. She harps on how I locked her out (never happened) day after day to my sister in law, who cares for them. After she came at me with her fists and threatened me, I will not go back to see my dad because of her. The family caring for her, my brother and his wife, need to get her help for this. What can I do to convince them that Mom needs help ASAP?
