Thyroid in Bittersweet

I saw the endocrinologist today. He explained the differences between armour and snythroid medications and decided the synthroid would be better for my instance.
He did a thryoid ultrasound in the office. And noted its double its normal size at the smallest part. no nodules or cysts. But im started on the thyroid medication. He said with any luck, getting the hormonal support will take the strain off the thyroid and my immune system so it stops targeting the thyroid. And at least maybe alleviate some symptoms.
So maybe ill start feeling like an adult and not like a toddler.
