Failing thyroid: Most likely you have Hashimotos thyroiditis, which is gradually "eating away" at your thyroid. Your doctor could check TPO antibodies. Your gland may not be totally dead now, but it likely will be eventually, but total hypothyroidism and a dead gland could be in 3 months or 10 years. Probably best to take your synthroid (thyroxine) to avoid the symptoms of hypothyroidism, but talk to your doc.
