What many of us and medics forget, is that hormones rise and fall naturally: when we get to peri they can go higher/lower = all these symptoms. R your symptoms cylical?
Keeping a mood/food/symptom diary may be of use to you, variations to discuss with your GP.
R U able to tell us which HRT regime U R using? Some find the progesterone part very difficult.
That's sad that U are unable to discuss with your husband

but at this stage of our lives we should not imagine what others may think or how they might react. He may B wondering why your moods etc. are as they are ............. ask him how much he is aware of menopause as an opening?
When R U next due for a med review? There are dedicated menopause clinics both in the NHS and private sector: there are long waiting lists to paying for advice mayB, your GP will have a clearer idea of what is required and should be able to prescribe what is suggested.
