Anna,
You don't say how bad your anxiety is but if it is interfering with your life and you are unable to function, then I say take the ADs. A slight increase in anxiety is one of the side effects of most ADs but even if that does happen, and it does not happen for everyone, it will only last for a few days. Would that not be worth it if they were to help you in the long term? Give yourself 3 months or more on both and then review it. You may then stop the ADs and continue on HRT only depending on how you feel. Quality of life is more important than the number of pills we take. When I was in the throes of it I would literally have taken anything to make me feel better (even contemplated waccy-baccy at one stage, that was how desperate I felt!). In the end it was a combination of HRT and ADs that got me through some very tough years.
