Where do I start?

Could you guide me on where to start? Im 52, have menopause (not fun), then I have constant headaches, lethargic ( absolutely no energy at all), and I always hurt. Like everywhere, and cannot explain why or even where exactly but its like fire or just a toxic feeling. I have your book!! Love it !! But where to start? I know I'm over thinking it. But any help would be soo welcome.
