Thanks for the welcome to the list. I know what you mean about feeling like you had gone off the deep end. I felt the same way. I really thought I was having a nervous breakdown as the symptoms kept appearing. I was stressed out in my life already and Graves’ just compounded everything. I almost went to a psychologist. I am kind of glad I didn’t becuase I may not have actually gone to a doctor then and my hyperthyroidism may not have been found out. I researched the breastfeeding and ATD’s quite a bit and decided that I did not want to take ANY chances with the meds passing through breast mile (although I understand the risk is very small). Weaning went very smoothly.
