Graves-Basedow disease is a medical disorder that may manifest several different conditions including hyperthyroidism (over activity of thyroid hormone production), infiltrative exophthalmos (protruberance of one or both eyes and associated problems) and infiltrative dermopathy (a skin condition usually of the lower extremities). This disorder is the most common cause of...

However, if the doctor was aware of the ground-breaking study jjbrookes linked for you, she would have done what ALL thyroid-savvy doctors do and look at your actual hormone levels to determine thyroid status, not pituitary hormone TSH.
Based upon your lab's ranges, a healthy person would have FT4 at least 1.25 if not higher - you are hyPO and need a lower dose.
(ATD dosing is always based upon the FT4 level. For whatever it's worth, no one would feel good with your FT3 level, either)
And, the doctor also demonstrates further her lack of knowledge. Just because TSI level greater than 140 usually means positive for Graves' and your level is lower does NOT mean you don't have Graves'.
Your level probably improved as a result of taking methimazole.
Healthy people would have TSI less than 2.
I don't know why she wants you to have a radioactive study of your thyroid gland - the test is outdated and inconclusive. The only thing it's "good" for is to give the nuclear medicine people a guesstimate as to how much radioactive iodine to use if you opted for RAI.
Here's an article written by Elaine Moore about the scan:

I guess she's not worried about exposing you to unnecessary radiation. (sigh)
The link that jj gave you is a medical journal of endocrinology. This is the stuff docs are supposed to be reading in order to keep current. Take that article in with you and insist the look at it. Make some noise if they refuse.
Hang in there snippy and keep looking for a good doc. It took jj quite some time before finding hers...but she did it. They are out there. Dont give up...Big Hugs...Kathy
