I don’t have hyperthyroidism, but I have all of the symptoms! What do I have?
I have all the symptoms of an overactive thyroid, but when my doctor sent me for a blood test (Thyroid function test), the test results came back normal. What is wrong with me? How can I have all the symptoms, and not have the disease?
Sometimes thyroid tests come back normal even if they are a little low. Go to the web site, "Wilson’s Temperature Syndrome." There’s a lot of information on the thyroid. I found it helped me.

Either it’s in your head, or you are diabetic. I’m guessing it’s in your head.
