I'm hypothyroid now! Radiation pretty much plummeted my numbers in 6 weeks, like an insane amount (I basically went from a -50 to 77). And now I have much clearer evidence that my depression was directly do to the plummeting hormones. Now starts the crappy part wherein I go on new medication to add back in what has been removed, but it's good to no longer feel like I'm completely out of control of my mind and body.
