Estrogen!

Do you know what happens to a young woman when her estrogen level drops (as it does approximately every month)? PMS, that's what. She feels listless and blue, she feels weepy; she is irritable and miserable.

Do you know what happens to a post-menopausal woman when she stops the estrogen pills she had been taking ever since her body stopped producing it? Why, she feels listless and blue, she feels weepy; she is irritable and miserable. Because estrogen is a feel-good drug.

And THAT'S WHAT'S WRONG WITH ME LATELY! Of course! Why didn't I realize it? I'm very grateful and relieved for this bit of belated understanding.

(But I still plan to stay off the estrogen, if I can adjust.)
