In general, the Paleo or Primal Blueprint diet does tend to help women with PCOS, who also have testosterone dominance. So perhaps start with just the basics as far as the diet.
It is possible that doing tabata-style workouts is a little stress-inducing. I think Mark recommends tabata or just regular sprinting only every 7 to 10 days. Then some strength training 2-3 times a week, but not for huge amounts of time. And most of the time very low stress stuff.
I don't have, or at least I'm unaware of, any serious hormonal issues. I was doing 2x a week of body weight exercise classes. One of them was really focused on strength exercises and form but the other mixed a lot of cardio into it and was sort of high impact. I got a lot more from the focused one. We are on a two-week hiatus from these classes and I've only been doing extremely slow running and biking (heart rate no higher than 133). I can't believe the energy I feel lately. I think when the classes resume I am only going to take the one strength class. I'm not going to bother with sprinting anymore. All that was just too stressful. I feel so much better with this slow stuff, like light years better. I share this because it's worth considering. Mark's an ex-pro athlete and a man. I'm not sure he knows what's best for women all the time. And personally, I think this focus on cross-fit and all this super high impact stuff is a little bit of "if a little is good, a lot must be better."
