yeah it does sound like you have met some whack jobs lol...
that being said... there is controversy over whether mental disorder is categorical or dimensional. if it is categorical then there is a hard distinction between mentally ill and not mentally ill in which case you would indeed hope that your clinician's wouldn't be mentally ill! if it is dimensional rather than categorical then there isn't a hard distinction between mentally ill and not mentally ill because it would be a matter of degree. still, one would expect clinician's to be more on the not mentally ill end of the spectrum lol.
freud was fairly novel in suggesting that we are ALL mentally ill, basically. i guess i figure that ideas, thoughts, desires, emotions, all of this stuff is healthy... where the unhealthy comes into it is what you DO with the stuff you have got.
but yeah, people thougth freud was a wack job because of his notion that everyone was pretty %#@&#! up really...
lol
