I have an elderly father who has always struggled with mental illness all his life. Over the past 2-3 years he has refused to take any medication. He has made our lives and my mothers lives a living hell at home. He is continually mentally abusive to our mother, has delusions, goes off on wild rants, breaks things in wild rages, never showers, makes verbal threats of harm to family members. It has gotten to the stage where family members living in the house all lock their doors at night because they are frightened. Can anyone suggest a way forward?
