I'd welcome any information regrading cortisol. A friend of mine, a psychologist, has an idea that some of my problems may be related to stress, which can dump high levels of cortisol into the blood stream. In addition, I found this:

Interestingly, it says that high cortisol can induce symptoms of hypothyroidism, or symptoms that mimic hypothyroidism.

Thanks.
