GypsyRoseLee really hope that the AD help ease things for you. What a journey you are on x
I'm not sure that lighter periods always means low estrogen, I have been down the road of thinking which hormone is up or down myself and got to the point where, in general it is very hard to be sure. If you haven't had any hormone testing on a consistant basis I think the best way to look at things is that there is an imbalance. I really know that isn't easy to accept, because how the heck do you solve it! But, I really do think in reality, all hormones are going up and down etc and given that HRT didn't appear to sort the problem enitrely, I think you are dealing with other things at the same time.
I have and am being treated for emotional trauma symptoms, I wasn't really aware of this when my own perimenopause symptoms started, which in hindsight I really don't know if they were classic or that everything going on (perimenopause and trauma) was just sending EVERYTHING haywire. Thyroid, adrenal stress, cortisol levels, estrogen, progesterone, blood sugar levels etc. Like you, I have had to tackle things bit by bit, like piecing a puzzle together.
I DO feel a lot better than I did, I think it is a combination of my body adjusting to new hormone levels (wherever they might be) & accepting that is something I cannot entirely control and my treatment for the trauma related anxiety. I also have no idea how long things will go on, I am also 45 and also had several years of very high stress before all this.
I say, treat the primary symptom and it sounds like the mood, anxiety and depression are key for you and your current approach is addressing that - try and leave the rest to do as it will (for now) and see what the AD's do over the next few weeks.
Please keep the faith that this journey of unknowns will end, you will come out the other side and hopefully memories of it all will fade. x
