Most Helpful Girl
"First, do no harm". Maybe this lesson will teach her that she should practice kindness towards others. But she is ultimately not responsible for anyone's well being other than her own (and young children, of course, if she has any). If he committed suicide he likely suffered from depression and other mental health issues. Even the best doctors, along with impressive combinations of therapy and prescription drugs, can't always prevent suicide. So she should try not to feel guilty. She can move on, and will be a stronger and more watchful person. A support group would really help her, I think. Being surrounded by other people who have been through what you are going through helps immensely.
