@Cliff Hanger,
No. We didn't understand anything about mental illness in his mid-twenties, but he did things that didn't make any sense back then. His actions became worse in the thirties, and it got to the point when I had to call the police to take him to the hospital. They held him for less than 24-hours, and told us to come and pick him up, because he was not a danger to others or himself. We tried to find an institution to take him, but could find nothing for the longest time. He once spent about three weeks in a mental hospital in Fremont (*where we once lived in the sixties). When he acted up again, we took him to another hospital where my wife once worked. We sat in the waiting room for over three hours. As luck would have it, a nurse working at the hospital recognized my wife, and she promised to get him admitted to their psych ward. They held him for two weeks, and another week a few months later. With meds and follow ups with psychiatrists, he has now stabilized for the past two years, but my wife continues to remind him about taking his meds. We also applied for public housing for him, but the waiting list is over two years.
