Thats excellent! (after a fashion)
Sorry, I read from your first post that some of the symptoms began before insertion of the IUD. My bad! I'd been up all night at work....
Looks like its just a hormone problem then!
I guess liver maintainance is a big step (as you know, liver is responsible for hormone balancing and breakdown) esp with oily skin, liver cleansing totally cleared mine!
And avoiding any phytoestrogens in food (soy, raspberry, licorice etc etc etc), to get your body back on balance. I assume you dont drink caffeine or take 'white' foods, perhaps try some gota kola or ashwagandha, both are nervine normalisers which may help ameliorate the anxiety / stress symptoms.
Did you get TSH and T3 and T4 from the previous bloods?
Best of luck!
