There are lots of posts on the health board about HRT and how to treat menopause symptoms.
In a nutshell, there was a study 20 years ago that connected HRT to higher breast cancer risk, but that study was flawed and the increased risk for most women in minimal. As a result, doctors, in general, aren't prescribing HRT and women, like you, are miserable. But if you can find a "menopause" doctor, you can get HRT - there are ways to make it very safe - and feel like an actual person again, instead of feeling like crap for the next 10 years.
Go forth and get HRT, my fellow traveler!
