Hmmm.. AN is about control, about controlling one thing because there is another thing (fears) that can't be controlled.
I think many of us here on a site like PC have emotional intimacy issues. I know I do.
There is a lot to it. Many layers to explore. Like a grid or a matrix, one thing affects another and as you work on "anything and everything" in therapy, the effect reverberates and healing happens over many areas.
When I began therapy, I read voraciously on all things I thought I needed to know. It was a defense and a distraction, and an effort to control the therapy (versus choosing the direction of the session). After about a year, I stopped reading and stopped trying to know something before I knew it.

It was later that I realized the reading and wanting to have an intellectual understanding was also... ready?... an effor to avoid the emotional intimacy of therapy!
