Are Hashimoto’s Disease, characterized by low thyroid activity, and Grave’s Disease, characterized by an overactive thyroid, actually different manifestations of an Epstein-Barr virus infection? If so, how can this be?

This is quite true. There is, in fact, a family of such viruses with varied effects and, depending on the level of aggression of the virus in an individual, there might be a diminution of thyroid function and loss of critical cells and function or, conversely, presence of an aggressive strain of virus might cause a proliferation of thyroid tissue to counter the suppressive effects of the intruding invaders, and thus result in an overgrowth and an overactive physiologic consequence. But, practically speaking, to use divine requests will not require any unique fine-tuning for one condition versus the other. Dealing with a virus is the key fundamental problem in both instances, and that can be done through divine healing requests.
