OH No! You may be PMS-ing and you may be overreacting, too, but she's dismissive at best, under these circumstances, even if there's no intended malice. The start of your menses won't change that, though I appreciate it may become water off your back when you're feeling more yourself...until next month, when she does it again:
Though I see the benefit of attempting to deal with it in one fell swoop as Mame suggests, I share osso's eek factor, if it goes wrong. I'd address it each time it arose, and figure she's bright enough to pick up on it. If nothing else it could become openly acknowledged, and at best, she'll take steps to emend it, but that's her deal. She
will learn not to do it with you, if she's called on it... or at least
I would, or at least I think I would.
If she's gracious enough to acknowledge it eventually, you might cut her some slack by adopting the mantra
"God have mercy on us power seekers."
I might eventually spell it out specifically at a later time, if subtlety (I thought my earlier suggestion was about as subtle as a hammer, but meh, maybe not) failed and she continued to undermine me.
Sounds like she had to become tough as nails to reach her position. I admire your ability to identify that, and your willingness to be so fair-minded, though I think you're being hard on yourself.
Besides, the devil's in the details. I really
do hate MAWve.
It's not what you say, it's how you say it, every single time.
