The doctor told me I have Hashimoto’s, an autoimmune disease of the thyroid. The thyroid is a small butterfly-shaped gland in the neck responsible for producing thyroid hormones. When your body cops a constant avalanche of stress hormones, your thyroid can get damaged and stop the thyroid hormone-producing party. Now, every cell in your body is affected by thyroid hormones, so when this happens, pretty much your entire body is affected, or at least all the parts of you that make you feel human.
