I was very similar, only started on a continuous regime in Feb (Evotel Conti) and felt the best I had in ages, then when I had to have some medical tests along with starting a new job I became increasingly anxious, weepy, terrified of going to work. I thought it would all go once things had settled down a bit, but the anxiety just seemed to stay with me.
Have now been a month on AD (Sertraline) and it is made a world of difference. Have had two people comment that I am a different person. Just had my first work appraisal and my boss said she had been quite concerned as I seemed like a rabbit caught in headlights but that now I seem like a completely different person, a bit more like the one in my CV. Also my DR at a review of the treatment last week made the same comment.
I've never been on AD in my life before and once I got over the initial nausea (side effect) I feel so much more calm - haven't had a weepy moment in a month.
The downside is that I have to stay on them for 6 months, my sleep is rubbish, I wake at about 2am every morning, however this was the case before taking ADs. I can't say that I'm happy, I don't seem to have a feeling one way or the other but I'm glad to be a little in control.
Not the answer for everyone I know. The Dr did discuss changing the HRT but I felt that it was working for me in the main part, no flushes and no night sweats or aches and pains, just a return of the pre-HRT anxiety.
