"Into The Wild" How did Carine react to hearing the news about her brother? (Be specific)

From the text:

“It’s your brother,” Fish had said. “They found him. He’s dead.” Sam, Walt’s oldest child, had called Fish at work and given him the news.
Carine’s eyes blurred, and she felt the onset of tunnel vision. Involuntarily, she started shaking her head back and forth, back and forth. “No,” she corrected him, “Chris isn’t dead.” Then she began to scream. Her keening was so loud and continuous that Fish worried the neighbors were going to think he was harming her and call the police.
Carine curled up on the couch in a fetal position, wailing without pause. When Fish tried to comfort her, she pushed him away and shrieked at him to leave her alone. She remained hysterical for the next five hours, but by eleven o’clock she had calmed sufficiently to throw some clothes into a bag, get into the car with Fish, and let him drive her to Walt and Billies house in Chesapeake Beach, a four-hour trip north.
