Dealing with a miscarriage?

I miscarried my first pregnancy at 9 weeks in late August/early September and tried again to conceive in the beginning of November, but the tests were negative. I've been struggling with processing all of this and just found out today that my brother-in-law and his wife are going to have their second child in 2 years. It feels like a weight hanging over me telling me that it won't happen for us. And to top it off everyone keeps asking when we are going to have kids. I feel so broken and can't even begin to explain why we haven't yet when they bring it up. How do you even begin to tell family that and your fears of not being able to have kids? How do you keep hope and faith when you feel so broken?
