What if we don't ever get a placement or match

I'm lacking in sleep, and my hormones are making me cry over anything. As I sit here and type I feel the tears. So I know I need some extra sleep. You know that Miley Cyrus song The Climb? "there's a voice inside my head saying you'll never reach it..." With every medication and procedure I was always told "this time will be different. this time will work...." By the last procedure I said "what if it doesn't work" and the doctor said "but it will.." Guess what it didn't work. What if we get approved by the state and they never place a child with us and we never get matched? What if we are one of those couples that they push along just to hush up, but "misplace" our file into the paper shredder.
