Maybe it's better to rephrase and say "if I think I am going to be fine then at some point I will feel better, but right now I am not exactly there yet." I think sometimes you get to the doctor and in my case I just don't know what to say when I get there because I feel a little intimidated. For this reason I usually bring a list so I don't miss anything. We all do those things that we question ourselves about afterwards. You can't go back and change it so I would not spend too much time fretting over it. Just be more honest about how you really feel the next time you have a visit.
