if it helps to have something to take with you to say, then you can always jot some notes. I tend to email myself a list of things I want to be sure to cover, but I rarely look at it unless I feel like I'm floundering (I can access it from my phone). The first session even with a psychiatrist is generally about 45 minutes so they can get more of your story. Most of the time, they will ask specific questions to get to the information they are looking for. They might start with "what brings you here today" but I find therapists are more likely to ask that question than psychiatrists.
