Can someone who had abnormal thyroid test results provide information?

My doctor recommended a thyroid test after I came to her with concerns about anxiety. She said that some of her patients that experience anxiety end up having wonky thyroids. Well, sure enough, my results came back abnormal.

It was a TSH test, and my question is, does this mean for sure that I have a lifelong problem, or does additional testing have to be done now?

I’m going to talk to my doctor, but I’m not sure she works today. In the meantime and to kind of put my mind at ease because I’m feeling pretty anxious, I’d like anyone who was diagnosed with hyper/hypothyroidism to hopefully share the process of your diagnosis with me.

Anyone? :-/
