My husband and I are renting a room from my mother. We decided to live with her while he completes some on the job training that has lasted for about a year and a half. My sister who is 25 lives in my mother’s house as well. When we first moved in everything went okay but slowly things started to get worse. My sister got in an argument which was half serious half playful and out of no where she picked up a dirty kitchen rag and threw it in his face. She immediately apologized and my husband and I left the kitchen. Flash forward a year later and my relationship with my sister has changed completely. We grew up as best friends. I am three years older than her. Late last year she had her first psychotic break. My mom took her to starbucks and when my mom went in my sister left the car and got into a dumpster. Then wandered around the streets. We took her to a behavioral health center and she went to the bathroom took off her clothes and tried to run out of the center. She spent 4 days in a hospital and then was released. They diagnosed her with psychotic disorder nos and sent her home. When she got home she started acting like her usual self for about a week.
Then everything went back to her staying in her room the entire day and she has stopped grooming completely. I can barely go into her room b/c the smell is so strong. I have asked her to take a shower and she said no. It has been over a month since she last showered or brushed her teeth. Every time she goes into the kitchen we can smell that she has been in there. My father was diagnosed with paranoid schizophrenia and he abandoned my family when my sister was still in the womb. My eldest sister is also schizophrenic so I believe my younger sister is suffering from the same disorder. My eldest sister stop talking to my entire family and also claimed we were trying to kill her and her children. I know personal grooming is the least of her worries but I can’t force a grown woman to do anything. I have tried to encourage her to go back to the doctor but she won’t listen to me. Whenever I go in her room it looks like she has been crying. She hasn’t changed clothes for over a month. How can I help her?
