Really ask for help! ! ! There is an old man at home who makes trouble without reason, and my family is about to break up. How to solve it?

I am also very helpless. My mother has been very picky since she was a child, and her neighbors say she is a troublemaker. Now I'm 86, not to mention I've taken care of it for eight years. It's hard to serve, just like Huang Shiren's mother treated Xi. Bullying that girl every day, she will cry angrily and make a scene if she is not careful. We are all worried to death knowing that our neighbors upstairs and downstairs will push their luck when they hear jokes. I really don't know how to face it. Said she stole from her, fed you a spit, and didn't wipe herself. Make her move and say, "I can still play around without dead people." Sometimes I say that you always make me sick. Why don't you leave before someone takes care of you? She replied: hmm! ? I didn't read it until I needed help. Why is this man so difficult to serve when he is old? Always say something vicious. Anyway, I only sleep for a while.
