Although I've never worked with another one suffered from schizophrenia, but I've spoken to some of their loved ones, and from what they described, I can tell it wasn't a pleasant experience at all. Like most diseases and illness, sometimes those around the person will suffer equally, if not worse.
You are right with that one mate, the family of the individual is also affected as well.
