OP, sorry you've been having a bad time. Yes to Menopause Matters. I was able to wangle a menopause consult on my work medical insurance scheme, so just giving you the download in case it helps:
They did a blood test which showed all my lady hormones were flatlining, but also that my thyroid had packed in (a common thing with women our age, so worth testing).
The hotshot Harley St. hormone expert put me on a) estrogen patches b) Mirena and c) testosterone, to add a bit of libido oomph but also, allegedly, mental clarity (this was a cream imported from Australia, not available on NHS, but there are other sources of testosterone.) And then sent me to an endocrinologist for a big dose of levothyroxine to sort out the thyroid.
Depending where you are, there are bits of the NHS that are less useless than others when it comes to menopause. There's a a menopause centre at Chelsea and Westminster hospital that's run by some brilliant people (I haven't been myself but know of them.)
HRT is not as unsafe as many people think. There should be help available for you. Depending on how knowledgeable your GP is, you may need to be politely persistent. You don't have to feel awful. Good luck...
