Vaginal Health & Diabetes

Aaleyah
So I've been dealing with such discomfort down there since about January of 2015. To keep it short, I'm talking back to back yeast infections, bacterial vaginosis, just overall discomfort & pain. I've only had 1 partner, who was my first, for 4 years. 
I don't use any washes that can throw off my pH, I wear cotton panties, eat yogurt, etc, etc. My gyno put me on the Diflucan pill & some gel for 6 months but symptoms are still very present. 
I went to the Dr. Again today & she thinks I may be diabetic because I eat SO much sugar that the yeast just thrives off of all the sugar I eat. Everything else is pretty much out the question (stds & all that). I do plan to cut back on my sugar intake & carbs, because I will admit that I eat an OUTRAGEOUS amount of sugar. 
I'm just curious as to if any one can speak on this? Any diabetes out there that experience ongoing yeast infections? 
Any suggestions for relief?
