I don't know that having a list indicates that you are afraid of not being sick enough. In my experience, ts are happy to see people who don't have a diagnosis of mental illness who just want to work on stuff.

There have been times where I have taken in pages and pages of journalling for discussion and (more often now) times where I don't take anything in. If it helps you to remember what you want to talk about, I think it is a great idea. After all, I take a grocery list to the grocery store, why not an issues list to therapy?
