Hi Twoodle,
Firstly big hugs, it's a horrible confusing time isn't it!
I am postmenopausal, on HRT since Dec 2015, my worst symptoms were anxiety, and bladder, also IBS.
You said you had the Mirena coil, were you ok on that? I have the Mirena and use two pumps bio identical estrogel daily.
It took time to control the anxiety, and 11 days is no time at all. I feel much calmer now than I have in years, my IBS is gone, and bladder is still overactive at times, but better more days than not.
Just wonderd if you could have kept your Mirena if it was working for you, as it is less systemic from my understanding, being contained in the uterus,
and you could have just added the oestrogen by gel application or a patch.
Regarding you bacteria levels, I make my own kefir and drink a small glass daily, it has been very beneficial in how I feel generally.
Have you tried valerian tablets or even rescue remedy to help you anxiety? I also found headspace app to be excellent at calming me when I was at my worst.
Hope you soon start to feel better
