Bless you, what a horrible time for you.
I don't find my HRT covers my anxiety enough, I need to take Citalopram too and that helps, though I have down days. I also have had days of feeling the chills or burning up, wobbly weak legs as if a bug coming on but wasn't. Often an upset tummy, loss of appetite or nausea too.
Also I didn't find patches helpful, couldn't keep them on so wondered about absorption.
Maybe you just need a differnt type of HRT? Have you thought of Utrogestan tablet and Oestrogel gel, its a combination that suits a lot of women. Theres a thread on here somewhere. I wouldn't give up on the HRT just yet there are many options and don't dismiss an anti anxiety med either even if it's only till you get settled on an HRT that suits. xxx
