Hi Hopefulone,
I am also 43 and am in the same situation. I had a hystorectomy when I was 32 years old, did HRT for several years, went off but am back on a very low dose of estrogen because I couldn't tolerate the hot flashes, night sweats, and smelling like a guy from the darn hot flashes. Getting older is hard enough without the darn menopause stuff. Hey, wait, getting older would be a breeze if it weren't for the menopause stuff. I am currently in the process of changing my diet completely. There just is not enough fiber and water in this world to keep my body working as it should.
Know that you are not alone and seek to find information any where you can. You may need to try lots of different approaches to find what helps you and what doesn't for all of your symptoms.
Hang in there.
