Ruining relationship

I cant seem to get it together regarding my miscarriage. I was 11 weeks, my husband is staying strong for me but he knows we didnt do anything wrong to cause it, it just happens but I have these days that trigger memories and it just goes down from there.

Any ideas to help myself pull it together?

Other than this we are a pretty normal couple but I feel like I cant be myself around him when I get really upset.
