HI, i'm new to your posting. I am 12 years post cancer and have recieved synthroid, at varied dosages over the years and with THS so suppressed I would say I was off the chart. So here is my situation. I was diagnosed ADD and depression aobut five years ago. Ok, that sort of made sense. So on a stimulant and a anti-depressant. I continued to expereince low level of depression, anxiety, and muscle pain. I just continued with live just living with the diagnosis and medications. Saw my endro earlier in the year I tried to ask him if I could still be experiencing symptoms related to thyroid. He said no , if anything you are slightly on the hyper side. So I went to mh primary care doctor who would not adjust the medications, he said that I needed to see a psychiatrist. So off I went to the psychiatrist, who gave me the diagnosis of Bi Polar. I have done so research on line and there is a link with thyroid and mental/psychicatric disorders. I was thinking tha surely I am not the only one to have been expereincing this. Please respond and tell me I am not alone or "crazy" I am just trying to figure out what came first =, The thyroid problem or the "bipolar" .thank
