Hi Alisar1,
I had a similar reaction to being on Evorel Sequi and eventually had to stop. I did not cope well with the progestin in the second 2 weeks (Evorel Conti weeks).
It is difficult to tell what is causing what sometimes. You need to decide whether you can cope with Evorel Sequi for 3 months to see if it settles. I couldn't, because I couldn't sleep.
Two things might be worth considering - get your prolactin levels checked if possible. Mine were sky high and so had to address that. Anxiety reduced greatly when that was addressed (using a herbal tincture of agnus castus via a qualified herbal practitioner). Second, you could try a different kind of HRT, e.g. oestrogel and utrogestan (both body identical). Loads of info on here and Louise Newson's site.
So much of this is trial and error, sadly. But there will be a solution for you. Hopefully you have a GP or menopause specialist who you can talk to and knows their stuff. If not, seek one out.
Hope you are able to find some answers soon. X
