Hi. It's the Change, does what it says on the tin.

hormonal upheaval can cause all kinds of unexpected symptoms including anxiety and depression.
R U able to tell us which ADs have been prescribed? A few are known to help with hot flushes for example as well as perhaps helping anxiety surges. If these are troublesome I suggest that your GP prescribes a dedicated anti-anxiety medication.
How long have U been on the Elleste? It mayB that as your hormone levels fluctuate the you require a hike in dose. Hopefully some1 will be along with HRT knowledge.
Some find that keeping a mood/food/symptom diary of use. How much of your symptoms are cyclical?
