Dealing with uncompassionate family after miscarriage

Literally it’s been less than 24 hours since I passed our baby due to miscarriage and my husband and his family are already asking when I’m gonna “get off [my] ass”. None of them have ever had a miscarriage so I guess they don’t understand that I’m still grieving as it’s not even been a full day but seriously how rude do you have to be. No I don’t have a freaking plan as to what I’m going to do next.

So now my husband and I are fighting. I just don’t understand how him or his family think that it’s okay to treat me like this.

Am I overreacting by getting so mad at them? I went to my moms house with our dog and I’m seriously considering divorce. Maybe it’s just the hormones?
