Hi and welcome TheQuietOne
You've had a tough time. Do look under TREATMENTS above as there are non hormonal prescription options that could be worth trying. My gynae recommends SRRIs like Citalopram for controlling flushes and low mood etc. but it can be trial and error before finding the right AD/SRRI but many women do really well on these.
Lifestyle is crucial when trying to cope without HRT. I'm 60 now, had an early meno, so had HRT for many years. I stopped HRT about 4 months ago because I was fed up with the side effects and I take Vitamin D3, Omega 3, magnesium, and now also St John's Wort, and I'm finding these helpful in many ways although nothing controls flushes like oestrogen. I do Mindful Meditation on the recommendation of my GP which I find great and I do a lot of brisk walking. Basically I have adjusted my life in many ways to cope with the meno symptoms.
