Miscarrying, how to cope?

I’m having a really hard time coping with this and go in for a D&E in two days. I keep crying when I’m by myself because I feel like it’s me being dramatic because the baby was only 8 weeks. I am beyond hurting and I don’t want my partner to see me cry or hurt for so long over this because he’s not. I have two little ones at home I have to be strong for as well, also have to let my oldest know she’s not going to be having a baby sister or brother anymore. Any helpful things to cope and also help with telling my toddler.

Also having hate for women who are pregnant and treating there body wrong.. is this normal?
