I have seen depression due to hypothyroidism treated with an anti-depressant. I am sure your doctor will be checking your thyroid status if you advise him of what you have observed. The case I have in mind could not convert T4 to T3 so medication with thyroxine , which is usually the first choice , was changed to tri-iodothyronine(T3)Result, no depression, and no need for anti-depressant.
