I'm posting this on my blog but I thought I'd share what's going on with me in this forum as well regarding hypothyroidism and how it can affect you in the same way anxiety can. I was diagnosed with hypothyroidism about ten years ago. At the time, I was having severe anxiety, forgetting things, unable to make even the smallest decision, felt overwhelmed, etc. It turned out to be my thyroid and I have been on the same dose of thyroid meds ever since. It was years later that I was diagnosed with panic disorder. In fact, when my doctor first told me, I thought it was my thyroid acting up again.
I had my doctor retest my thyroid two weeks ago because I had been crying alot, losing hair, felt depressed, had insomnia, was forgetting things and generally felt I was sinking back into anxiety and depression. These symptoms had come and gone over a period of three months or more. I finally was able to see my doctor--after about a month's wait. It turned out my TSH 4 levels were twice what they should have been and my doctor upped my medication for the first time in a decade.
It takes about 6 weeks before the thyroid medicine really takes effect, and right now I am still not sleeping at night, feel fatigued and have a racing heartbeat off and on. I also have short periods of anxiety and I pray through them.
Because the symptoms of hypothyroidism so closely resemble anxiety disorders, I thought I'd share the link to a booklet from the American Thyroid Association that explains all about it. I felt better after reading it. No one had ever fully explained hypothyroidism to me before. Someone on here may need this information, too. Especially the part about what foods not to eat or what not to drink in conjunction with thyroid meds. You can download the pdf and read it at your leisure.
