Why do you feel bad? My first CDC was a nice person just like your but was exactly the same as your...I went in got weighed, got my pre packed order and left (actually I was almost bundled out the door most of the time). Although she was a lovely person that just wasn't enough for me, I need someone to talk things through with, I needed someone who would listen and show they understood exactly where I was coming from and offer me advice on how I should deal with my issues.
My current CDC is my angel (god I hope she doesn't read this!lol), she gives me exactly what I need and has helped me deal with so many of my food issues. If you need more than to be weighed every week then there is no shame in mentioning that to her, it won't be the first time she's heard it I promise you.
