my experience with a CPN isn't good as i had a CPN and a social worker come round one day a week as part of a crisis team because i was feeling extremely suicidal and all they did was talk for more or less an hour then bugger off home leaving me with very sharp objects still on the table we was sat talking, so for me they weren't any good.

i have come to learn that psychiatrists and CPN's only nod there head and talk about what meds to dope you up on next.
which is strange as everyone i know that has seen a cpn says they are great must just be the area i live in i guess.
