Polycistystic Ovary Syndrome affects a very large percentage of women, but it's a highly under-diagnosed syndrome. It took a long time for me to get diagnosed, though I had all of the classic signs, and I've only just found a doctor who's taking me seriously, though I've probably had outward signs since I was 14 or 15.
This book is making me realize how very insecure I've been about certain things, but more importantly, it's helping me to realize that it's not just me. It's not my fault. And I'm not a freak (at least not for THESE reasons).
And that's after reading a total of maybe 5 pages in a 400+ page book.
