This is my very first post on the forum so I'm not sure what I'm doing,
First, I'm so very sorry about the loss of your grandchild. What a devastating loss for your whole family.
In doing a quick search, I came across a website that looks reputable that helps people with miscarriages', stillbirth and early infant death. https://www.tommys.org/
You have taken the first step by reaching out for help. I would call my physician for help with the depression.
Do you have a clergy person who might help with grief support? Perhaps the hospital has a group? A close friend or family member?
Secondly, reach out to your surgeon's office for diet support. You have to take care of yourself in order to help your daughter.
I wish I had some words to take away your pain. Please be gentle and kind to yourself as you navigate through this.
