I'm so sorry for your loss, it's heart breaking.
I lost my daughter 5 years ago when she was days old (unexpected illness after her birth, died in neonatal). It's truly the worst thing in the world.
I too suffered such fear afterwards, I couldn't watch tv or read etc, slowly I began to watch things that I carefully selected, nothing with babies or pregnancy, I'd watch tv on record so
I could faster ward all the adverts incase a baby advert came on.
I was terrified to go out for such a long time, mine was mainly fear of meeting people who excitedly ask if I'd had my baby. I started going out by driving miles to a supermarket in another town to lessen the risk. I complete appreciate this is not as easy when you have other children.
I know it's been said but honestly sands are wonderful, they helped bring me back and have played a huge part in making me regain my confidence and become more stable and deal with what happened.
I have also made lifelong friends through sands who I can talk and talk to.
The early days are hell. It's exactly as the other poster said, trying to live a new normal, things will always be changed but you will learn to deal
With it and sadly how to live life without your precious daughter.
Sands forum is a great, safe place to start accessing help, read until you are ready to post.
