And the people with the mental health issues tend to not talk about it either. I know of three members within my family circle who effectively clam up and refuse to discuss it.
It is hereditary and it manifests itself in many different ways. Things are better than they were 40 years ago and the meds are far better which makes it odd that these serious issues are on the increase; likely because individuals and their families refuse to confront the mental health issue and get proper medication.
