Feeling down.

In need of some positive words. My husband and I have been trying to conceive for 2 years now. We finally got pregnant back in April, and sadly lost the baby. I suffer from PCOS (polycystic ovary syndrome) so when we lost the baby I knew it had to be from that... 
I feel like I am failing as a woman, I can't provide a child for my husband and I. I am only 22, yes still young, I know!! But that is what worries me. I can't have a child now when I'm "most fertile", will I ever?? 
And with the months ticking by I can't help but to continue to mourn the loss of the baby. I feel like I'm going crazy because no one in my family truly understands what I'm so frustrated over. 
I just need some positive words <3
Thank you for reading.
