Many people (more common in women) that suffer from hyperthyroidism have a common denominator, that is they have a conflict over not having enough time, too busy, too much to do, "I can't do it all, but I keep rushing".
The thyroid accomdates the mind by becoming hyper to try to keep up with all the hurry and rush.
Overcome the conflict of the hurry can't do it all and the thyroid will heal.
