Writing on the forums like this is a great way to help organize one's thoughts, I agree. Often, even our self-contained efforts can help someone else who reads them though, they'll get an idea or notice something similar to what they feel or do and be comforted that others feel as they do or even energized to try another tack with their own problems.

You could print out this post and take it to your PDoc to read? That might give her a more spontaneous idea of what you are like and what you want and may need than a neatened up, mapped out speech? :-)

It sounds to me from this post that you'll do fine, whatever you decide to tell her because you are aware of the difficulties and some of what you feel and want, etc. I hope she does as well listening and understanding.
