I am incredibly sorry for the loss of your sweet daughter. Nothing can prepare you for the loss of a child and no words can make the grief journey shorter or less dark. We have a board for late pregnancy losses, as well as infant/child loss. It is the left above military families and is just called "Loss". When you are ready, I strongly encourage you to come there. Being able to talk to other ladies who had been there was invaluable to me when we lost our daughter Grace in May 2011. It is a very supportive place and will give you a good outlet to process.
I would also recommend the books Grieving the Child I Never Knew, Empty Cradle Broken Heart, The One Year Book of Hope and Good Grief (by Westberg).
I would also encourage you to seek out a grief counselor or support group, even if you think it is not needed. It took me 8 months to go, but was very helpful when I finally did.
Again, I am so, so sorry for the loss of your daughter.
