Questionnaires are simply tools you can use to look at yourself and your behaviors. From what you've described, it sounds like these tests are picking up on your past experience with an ED. Maybe you're not in the throws of an ED now, but I think it's impossible to overcome completely. Someone that's struggled with anorexia, even after recovery, might worry about their weight more than the average person--the only difference is that a recovered anorexic won't necessarily indulge in these worries and begin restricting again. The thoughts are always there--the issue is if you act on them.
Ask yourself this: is food in control of your life, or are you in control of your food? Do you live to eat, or eat to live? Answer them honestly, and you'll know for sure if it's something you need to discuss with your T.
Good luck.
