You have Hypothyroidism.
It will last you your entire lifetime and you will end up taking medicine every single morning. You can't eat food within an hour before or after taking it, so no more breakfast for you.
1)Insufficient production of thyroid hormones.
2)A pathological condition resulting from thyroid insufficiency, which may lead to cretinism or myxedema.
This really just means that my body isn't producing enough thyroid hormones so it produces more antibodies to destroy my thyroid. I have a slim chance of ever getting over it.
I inherited it from my mom's side, most likely.
