Need encouragment

Hello. Here's my story.

Five years ago my brother had a brain aneurysm. We prayed and prayed for him to be healed. He died. Just a year ago my mom was diagnosed with cancer. Same thing, I prayed and prayed for her healing. She past away. We have been ttc for 17 months now and I have prayed and prayed to be blessed with a baby. I'm feeling like job and my faith is being tested!!

I don't know how much more heart break I can take!
