Difficulty getting pregnant (PCOS)

I lay awake often (like now) praying that I'll be blessed with becoming a mom. I am a stepmom, but neither of the boys call me "mom", and I truly yearn for the day I'll have a son/daughter that will. Since I was younger, I've always pictured me being a mom, and those moments have never ceased. I have been diagnosed with PCOS since I was 19, and honestly at 36 I feel sad that I may never get the moment to give birth. It's extremely discouraging and depressing. I've tried many natural herbs, losing weight, etc that could possibly help, as I don't have the money for treatments, but nothing has worked. Ladies, does anyone have suggestions that helped them or someone they know? I will try anything! Thank you in advance.
