Heartbroken :-(

I went to pick up my offical ultrasound results today and went to see the Dr. The lady yesterday was lovely and showed me the heartbeat, but obviously didn't tell me the full story, I guess they're not supposed to. My Dr looked at the results today and yes there is one healthy little bubba, but there is also a 'non viable second twin' roughly the same size. This was our twins and yet one is dead. At the moment I am just so stunned and confused. Why would God prepare us for years with dreams of twins if we were only ever gonna get to hold one of them? It might seem ungrateful to be sad about losing one baby when there is another healthy one in there, but that was my bubba and I'm heartbroken. I have an appointment to see an obstetrician tomorrow and I guess will find out then what they do now, I don't know if they have to remove it or not. I would really value prayer right now :-(
