No, what you wrote isn’t stupid!!!!! The first thing that comes to my mind though, is, “How do you FEEL?” That, and what does your dr. say?
One of my biggest frustrations so far has been that how I am feeling and what the “numbers” are saying don’t always match up! The endo at the conference said that different people “feel best” at different combinations of T4 & TSH levels. At the time I thought how nice it would be if I had known ahead of time what those magic numbers were for me so I would have something to “shoot for”, so to speak.
