I've recently come off hrt after being on it long term (early menopause)...and I feel like hell. I have fibromyalgia and everything I was already struggling with is now far worse, headaches, ibs, aches and pains, dry eyes...the list goes on and on. Thankfully the hot flushes pass quickly...just as long as I'm not in a long supermarket queue wearing four layers of clothes! It's at those moments I'm convinced I'll self combust. :o)
That said I don't want to go back on it, there has been breast cancer in my family. I'm not sure I'd recommend it for anyone who's at the correct age for the menopause, the chances are you'll feel as bad, if not worse, when you eventually come off it anyway and you'll be dealing with it all when you're older!
You've already had some good advice, I wish I had some more for you but you're not alone...keep calm and carry on :o)
