Prediabetes with PCOS. Which came first, and does it even matter at this point?

Latest report: fasting sugar 108, HbA1c 6.1. My doctor said the word prediabetes and moved on to the next point on her list as if it was nothing. For me it was not nothing. I have read enough to know that insulin resistance is the thread between PCOS and diabetes. I have also read enough to be tired of reading. What I want to know from women who have both: did you manage to reverse the prediabetes part? What did your daily food actually look like, in a Bengali household where rice is not optional? I am willing to change but I need it to be realistic.
