My son is trying to keep his family together. His wife is showing signs of schizophrenia & has for along time. She does not like people , her few jobs last a few weeks at a time, due to something wrong with her boss, etc. She attacks me with unvalidated accusations as being uncaring toward our grandkids. Although the other grandparents aren t as involved as I am. She also talks about her parents lack of Participation in grandkids activities , etc. so it s not just me. She also has been extremely jealous of her sister in law. She is taking Klonopin. I am not aware if she has had a professional psychiatric evaluation & diagnosis for this medication. This past weekend, along with a alcohol consumption, she drove & now has a DUI. Now my son has to contend with her DUI along with her rational behavior and mood swings. They have 4 children, and I am concerned for their welfare , thank heavens they were at home and not in the car with her. Any suggestions?
