Never ever about individual clients, even anonymously. He has said things like "I have seen this medication be helpful to other patients" when prescribing my meds, or "I have met with people ten years older than you who started doing that" when I've said that at the age of 40, it's too late for me to do this or that, but those occurrences are very rare. He has never mentioned anything that anybody else has said to him, thank goodness, and he never tries to suggest what I could do by using what others say or do. I could not trust him if he did.
