Hi. I don't have answers for you, but just a couple of quick pieces of information. First: Prednisone can cause the emotional symptoms you describe; but second, it is extremely important that you don't stop taking it abruptly.

I don't know if it's the Prednisone that's making you feel like this. It could be, or it could be something else. I believe all MG patients should be tested for Graves disease, which sometimes comes along with MG. Graves causes your thyroid to produce too much hormone, which can make you feel the way you describe. It can be diagnosed by a blood test.
