Your TSH can be "sub clinical" and still be VERY HYPO. Please check out http://www.stopthethyroidmadness.com
and read everything. Ask your doctor to order all the labs she recommends, and do the adrenal fatigue self-discovery test. In the mean time, you can add Iodine (lugols iodine) or iodoral, not kelp, selenium and l-tyrosine to help your thyroid. http://www.iodine4health.com
