the girl who was involved in a suicide

Hi. There was an accident that a university student got hit by the lady who was leaping to death in this morning. The lady died in a moment and the girl fell into a critical condition. Suicides are wasting of irreplaceable lives. Do you know how the people who was left behind feel? It is horrible... I know how it feels. The lady did not know the feeling so that she could leap to death. Also in this case, the lady involved in another person. It is the worst case of the suicide. The lady sholud have thought about it.
