Why do some miscarriages affect people worse than others?

I think it all depends on how far a women is and how much they wanted a child to begin with... WHen your pregnant you automaticly grow a bond with your child. When I was 14 I had a miscarriage and it had no affect on me then at all. I had a stillborn which is compleatly diffrent because she was full term and I held her and everything but it did ruin my life. Others have miscarriages after theyve seen there baby in ultrasound name there baby and then its gone and it hurts wondering what was your baby going to be like... look like.. sound like ... I hope this helps.
