Not sure if I can go...

I am a wreck. First thing, I just awoke after working an overnight...maybe four hours of sleep, which is hardly enough. I'm not sure how I can go the doctor's appointment & lay there and actually pray more than I already have in the last 7+ weeks.
What if its bad news, but yet it could not be. Its like tossing that dime wishing for something, that's already is or not. I'm just not sure how I can do this....
