Losing my little nugget

Courtney
Hey everyone,
I'm new to this page and it's good to see so many supportive women here 
I found out last week that my baby is very sick and will not make it after birth. We are 22 weeks and have to have a D&E on Thursday.  
This is my second pregnancy (my first ended in an MC at 6 weeks). I was sure we were in the clear with this little guy and then the 20 week scan showed 6 heart anomalies and a spinal defect.  
We are devastated and trying to cope. 
Anyone that have gone through a D&E have any advice?  They told us we can try again 2-3 months after if we are ready. 
I'm so nervous to lose my little one and nervous to start again.
