Re: I don't know whether to take what my doctor prescribed for these test results

 Be careful with thyroid support.  I can't even take Kelp.

If the adrenals are weak, then even normal thyroid activity places an excessive burden on them. One may begin to feel 'hypoadrenal' (coldness, weight loss, dryness, fatigue, insomnia, and/or anxiety) and then the body innately turns down its own thyroid energy production by increasing production of RT3.

Even the Iodine you are on my be a stressor for your adrenals.  Be careful....and make sure you keep a good log book so you can track an changes.
