Look into treatment of Paul Nachbar

My friend Paul Nachbar has been in the mental health system for over 20 years and it has destroyed him. He was a very good poet very sensitive and thoughtful. That was his poetry from before he got overwhelmed by his treatment. Now it is very rough and full of anger. Sometimes his poetry comes near to its former self. I have been his friend for about 5 years and he has gone downhill in that time. I am very worried for him.
