Welcome to the community Amy.
You'll be supported here.
Yes, your understanding is right. Some people are lucky and can last their whole life and not have a destroyed gland, but others, myself included, suffer and lose their thyroids to the antibodies.
It does take time for the medication to kick in as you know, and hopefully for you it will ease some of the symptoms. Often the thyroid will settle down, and the antibodies will still be there, but not with such force.
Good luck!
I am not sure but wanted to stop by and say hi and welcome you to our community~!
