Missed miscarriage

I went to the OB yesterday concerned about some very light spotting. I really didn’t think I was going to get the news I got. Baby had no heart beat. I should have been 11 weeks but baby stopped growing at 9w2d (literally right after my 1st US where everything was fine. I have my D&C scheduled for tomorrow. We were suppose to tell our families today. It was suppose to be a happy day and now I just can’t stop crying. It is so crazy how things can change so fast. I just want to fast fwd through this all. How do I cope? How do I move forward?
