My adult son's father was diagnosed with manic depression 30 years ago and can become abusive.. He was seeing a psychiatrist for years and lived in the City. He moved to the country and stopped taking his prescribed mental health medication. and stopped seeing his doctor. I saw him today and he was nice then switched quickly to being belligerent. I asked about his meds and he said he quite them a over a year ago. I don't think he realizes his behavior is affecting the family. I think his son should contact his doctors and start getting involved. One thing scary is he is 65 and the State has written to him to please stop speeding because he has so many speeding tickets. I'm thinking this is not safe for our roads. Anyone out there with some advice?
