Take time and read some of the posts here. You will find that you are Most definitely NOT ALONE!!! It sounds to me like my story... and so many others. It seems that the Thyroid is a tricky little thing... intended for the sole purpose of making us think we have lost our minds. The good news is that you haven't!!!!
I have only been posting to this board for about a week. And it has helped a great deal. There are a lot of wonderful people here, who really UNDERSTAND ... they have been there and done that... so to speak. They also have a great deal of knowledge to provide.
When you get your lab results... post them here... and i am sure someone will be able to explain them to you.
Read others questions.... and what really helped is the post at the top of the page where people share their stories... I read for hours... and realized I am not Alone.
Good luck with your test results... and happy reading
