How do you find hope?

Michelle
Supposed to be 8weeks tomorrow and the doctor just called and said my levels are going up but not how she wants. She said a second miscarriage is inevitable. I don't know what's worse at this point, trying to hold out hope that since the levels are going up she's wrong or give up and let go of the hope? 
Any success stories or prayers would be greatly appreciated at this point. I just don't know anymore.
