@Dotty - things can be much more complicated because we are really in the dark ages with all this, in fact we are all pioneers thanks to the WHI putting the brakes on this for decades.
In my own case, anxiety (as with you) got worse initially with each increase in estrogen. So of course I assumed it was being caused by the estrogen and I stopped it. All my low estrogen symptoms returned and the anxiety didn't go away. So I restarted HRT and, this time, felt no worse with each increase. I have no idea why. Since I had explored no HRT, low dose HRT and average dose HRT, I decided the only unexplored thing remaining was getting levels up. So I increased... and hey presto, all my anxiety went away. If you try to reason it, it makes no sense - why was anxiety not a symptom for me UNTIL I started HRT? But stopping HRT didn't stop the anxiety? And then getting levels HIGH got rid of it??
This is exactly what I mean. We can't reason this stuff yet, because we don't have the research. There is only trial and error and working through different combinations of things, systematically. Best not to assume things, because they can be wrong and we might not try the one combo which works. And one thing many women don't even get to explore, is those higher E doses.
@Starfish - don't accept being told that you have 'normal' estrogen levels, because that is completely meaningless. Request all the actual results of your blood tests - which you are legally entitled to ask for copies of - from your doctor. Look at all the results. Anything under 270pmol is LOW, by anyone's standards. An average-ly acceptable level for many women is between 400-650pmol. And some women need to be between 650-1000pmol to get relief. It is very individual and involves trial and error.
Personally, I had inner tremors through the night which would feel like the bed was moving under me, hypnic jerks every time I began to fall asleep and my heart would beat incredibly hard and fast in my chest through the night - even when my estrogen was around 450pmol. NHS doctors would all tell me my symptoms most definitely could not be due to menopause or estrogen with levels like that. Only Newson Health told me they wanted me to get my estrogen up and see what I felt like with it much higher. As soon as I got to around 600 I noticed a huge improvement and even more around 800pmol. I now sleep about 7 hours a night and get 1 hour of deep sleep (according to my Apple Watch). Previously I was getting about 2 hours of dozing and I was a zombie every day. The NHS would have put me on pregabalin or gabapentin or SSRIs. I take nothing other than hormones at the moment (including for my thyroid). I am still not 100% perfect, in terms of sleep - I should be getting over 8 hours, I still have very faint tremors and I wake many times a night but I am able to go back to sleep now. I will be trying to get slightly higher to 1000pmol - except now there's an Estradot shortage so I might have to wait...
