Esspee, the menopause is entirely natural - and, for some of us, relatively trouble free. It's not like some severe vitamin deficiency, where something lacking has to be replaced. It's not a medical problem - just a natural process.
HeatherGirl, I agree with those above who've said 'Speak to your GP' as anxiety can be a medical problem. A student of mine was on antidepressants. Talking therapies hadn't helped. She'd been so very scared, felt low and hopeless.
The tablets made a marvellous difference. She had all the same problems - but felt happy and was a different person. I thought, at the time, that if I ever felt that awful, I'd ask for the tablets too - why not?
