Reactive hypoglycemia

I am amazed about the book Potatoes not Prozac and it describes much of my reactions to sugar. I am only 32 but have suffered from sugar sensitivity since I was very young girl, so it must have a genetic component. Along the 20+ years of misery I thought I had depression and bipolar disorder and had terrible choces of high sugar foods . I've since learned it was sugar sensitivity. I have a few questions as I make further connections.

Can this sugar sensitivity be the cause of my reactive hypoglycemia? My thought is that the sugar sensitivity over the 2 decades has made my sugars react to high and drop very fast (my blood glucose will drop 100 mg/dl in a half an hour to hypoglycemia levels). The OGTT test showed a normal fasting insulin, a weak insulin 1 response and an over-reactive 2nd insulin phase).

Can this sugar sensitivity be the cause of my pcos (polycystic ovarian syndrome)? I can actually feel the insulin response affect my ovaries when I eat any carbs. My thought is, is that my insulin receptors on my ovaries are being affected by my over reactive insulin.

Thanks to any info you have
