heh. sounds like your original doc was a little crazy him/herself.
mono-polar?
That would literally mean you were either manic or depressed all of the time and you wouldnt even be capable of feeling otherwise... At least, that would be my impression of the term 'mono-polar'
To answer your question, no. I have never heard of the diagnosis of mono-polar.
I've never even heard that term before.

Good luck otherwise
