I will post my lab results and ranges when I go to my next appointment. I called the lab where I asked for their ranges and the lady wouldn't give them to me. Confused the heck out of me.
Yes, it's possible that you've been taking anti-depressants and anti-anxiety, med for years when they may not have been needed.
Autoimmune thyroid disease can often cause symptoms, long before labs for Free T3, Free T4 and TSH show a problem.
Can you post your actual thyroid hormone levels? If you could do that, and include reference ranges, which vary lab to lab and have to come from your own report, it would allow us to better assess your situation and comment more fully.
I have Hashimoto's, which is another autoimmune thyroid disease, and I feel like I had it for, at least, 20 yrs prior to diagnosis. For years, I believe I swung from hyper to hypo, with periods of normal in between, until finally, in early 2008, my TSH was at 55+ and there was no denying that I had a thyroid issue.
