I found out what is wrong with me…
Menopause
Apparently, since I have been nursing, my estrogen levels have remained significantly low (as they should) mimicking a menopausal state. Even my “fuzzy thinking” can be explained by the lack of this hormone. Who knew! Probably every woman over 50…
So I will have these symptoms until I wean. But I feel much better knowing that I don’t have a brain tumor or hypothyoidism and that I’ll be back to “normal” as soon as I stop nursing.
