Pig depressed after stillborn birth

I have two pigs and male name sausage at a female named pork chop. pork chop just gave birth to stillborn piglets 2 days ago and now she's extremely depressed. she won't eat all she just lays there crying. She ignores me when I call her, she doesn't accept any treats, she barely gets up and walks around I'm worried about her. I've tried to sit in her pen with her and tried talking to her tried giving her treats tried comforting her I don't know what else to do sausage is somewhat depressed himself but he's still being social but I'm worried about pork chop she's acting like she's just giving up
