KAH, there is no way you should have to put up with these symptoms. I don't know how you are placed financially but can you afford to seek the help of a private menopause specialist? This comes up on here time and time again and I find myself saying the same old thing, if you don't get any joy with your GP, take control of the situation yourself and see a private specialist, it is worth every penny.
Your are clearly menopausal and you need to get it treated as soon as possible and not have your time wasted by a GP who clearly doesn't know what they are doing. I know you shouldn't have to pay to see a menopause specialist but what else would you spend the money on that is more important that this?
