I understand exactly what you are going through as well. I also have PCOS and I am also prediabetic. I am married and we are currently trying to get pregnant. I have been getting treated for it for 1 year now and if there is one thing I have learned is everyone reacts to things differently. Also I have learned that jut because you have it doesnt mean that you are infertile. I am on different meds but the biggest thing the doctor has told me to do is watch your diet. I am overweight and have been trying to control that with different diets throughout the year but have recently learned that you majorly need to watch your carb intake. I have not lost any weight in over a year but since being on this diet for 2 months I have already lost 15 pounds. That is the best answer I can give you. I know it is not to comforting but that is all I have. Also if it helps I have heard a couple times throught this year that even you loss 5% of your body fat that ups your chances fertility by like 50%. Just keep that 5% in mind and keep that as your goal. I hope everything gets worked out for you.
