How to cope with a stillbirth?

Monday afternoon, we went for an ultrasound and found out that our baby girl had no heartbeat. I was almost 24 weeks pregnant (6 months). Yesterday, March 2nd, I delivered my beautiful baby Sophia Annaliese who weighed 15 ounces and was 11 inches long. I spent most of the day with her yesterday, holding her and crying. She was so perfect in everyway other than her large gastroschisis (opening of abdominal wall) which led to heart failure. She was so beautiful…. so small but so perfectly formed. We already knew she likely wasn’t going to make it but didn’t know it would happen so quickly. I’m home now. I was discharged from the hospital this evening.. I can’t stop crying, I’m having a hard time caring for my 4 year old daughter and I don’t even feel like I want anything to do with my fiance. He is taking the news a lot easier. Tomorrow we have to go pick out an urn for her ashes and I don’t know how I’m going to get through this. Has anyone had a stillborn baby? I don’t know that I ever want to try and get pregnant again…. Is that normal?
