My endocrinologist diagnosed me with
Graves Disease based on the low TSH and high TSI. However, the only
symptoms I have are fatigue and possibly anxiety, although I don't have anxiety in general--usually just around exam times. If anything I am more sensitive to cold than to heat (and have always been), absolutely do not have trouble sleeping (it's waking me up that is difficult!), and have never in my life LOST weight. I have gained 5 or so pounds in the past year..
