I guess I just need support

My husband and I started TTC in December of 2016. We decided that we wanted a family the month before so I stopped taking my BC pill (I had been on it for 8 years). It’s been a long time, but I’m still left empty. I am doing all the things that seem right, I am exercising, eating right, cut out alcohol and other nasty food items. I’m healthier than I have ever been. I have tried prenatals, preseed, i have tried not trying! I have used OPKs, we have fucked like rabbits, we have cut sex down to only the day of positive opk! I have been steadfast in prayer, I have been to a doctor and so has my husband and gotten a clean bill of health. I have taken any and all medications offered to me by a doctor. Yet I am Still not pregnant. 16 long cycles. I am just left feeling broken, I feel inadequate, I am bitter and angry that it isn’t my turn. I have lost hope. I feel it will never be my turn. How do I get my faith and hope back? How do I continue in this journey without losing my mind?! How do you ladies do it? Please give me some advice.
