Though it has no cure, it CAN be managed. And good for her! Knowing what it IS so young! I got a partial ammenorhea dx at 16 but not the full PCOS/IR scene til 26. I'm finding the support in my 30's much better online and in person. Still not ideal in my area, but WAY better than it used to be. Hopefully your area is a little better.
In my first ten years without knowing what I fully had, I know I made some mistakes -- not enough exercise, too many carbs, wrong type BCP, etc. So yeah -- those teen/20's years are a good time to get it under control if you know what it is you have. So much more info available than there used to be -- esp online.
