What do you think of this?

So apparently this woman, who's 23, was living with her very sick mom. She wakes up and moves to the living room, peering into her moms room on the way. She sees her moms visibly not breathing. She stands there, then continues to the living room to mess with her phone for a few hours before calling 911. Never goes back into the room or makes a attempt to see her mom. Obviously she was in trouble when the cops find out. She stated she just knew she was gone and couldn't handle it. So she just tried to ignore it for a while and pretend it was like any other morning basically.

Should she of tried to save her mom? Or do you sympathize with the daughter?
