Miscarriage struggle

Went to the doctor yesterday for my 12 week ultrasound and found out there was no heartbeat and baby was measuring at 9 weeks. I guess they call it a 'missed miscarriage' because I've had no symptoms of miscarriage - no cramping, bleeding and still have pregnancy symptoms. I have to go in for a D&C this Friday and still knowing that my baby is inside of me is so emotionally draining. 
It feels like a bad dream, I'm still in shock and don't quite know what to do. I was just starting to feel excited that we had made it this far and we were going to announce this week. 
How is everyone coping with the loss? I honestly feel like sleeping all day and have no motivation for anything. My husband is upset too but keeps trying to help me feel better and wants us to get out of the house and do stuff to get our mind off it but I honestly have no desire to go anywhere or even get out of bed.
