Hi Diamond and welcome.
I can only speak from my own experience but HRT has helped enormously in addressing the symptoms you are also having. It also helped with anxiety which was another symptom of mine and one which many women don’t associate with menopause.
Yes you do need to take a progesterone alongside to protect your womb lining. There is lots of info on Dr Louise Newson’s website -menopausedoctor.co.uk. You normally start on a standard dose and need to give it 3 months to see if it makes any difference. The dosing can be trial and error as I have found, one size often doesn’t fit all but for me it’s been worth persevering for the many benefits it provides.
Good luck, let us know how you get on
