Common Burial.

So I recently had a MC (April 26) I’m still trying to cope with everything! This has by far been one of the hardest things I’ve ever had to go through. I was 12 weeks when I lost my angel baby. I’m still so broken over it. Recently my father in law told us we have to come over(Saturday June 16 the day before Father’s Day), the same day as our common burial for our angel baby. I kindly told him we wouldn’t be able to make it, due to us having a common burial, and I would like to spend the day with my husband afterwards. I don’t want to go anywhere afterwards. His dads response was how can you bury something that doesn’t have a body. After I passed the baby I had to save it so it could be buried. It has me all over the place right now. Currently balling my eyes out, and heart broken that someone could even say something like that to someone going through what I am... that was my baby, yes it has a body. I have ultrasound pictures of it and it was a baby, it had arms, legs, a head, and also a heart. It may have not been beating but it was all there! How do I respond to this, do people not realize just how hard miscarriages are and how much emotional pain people go through?
