She might have had a sad story related to her family. Her family didn't support her singing career at first. They thought it was a waste of time.

Well, here's a possible sad story. The jewel singer was in a relationship with someone who was very controlling. He didn't want her to pursue her music career fully.

Financial problems often play a role. Some scientists are so dedicated to their research that they forget about their own financial stability. They may struggle to get funding for their projects and end up in debt or poverty, like Nikola Tesla. And also, sometimes the society's values can be a factor.

His heliocentric theory was against the Church's dogma at that time, and he faced a great deal of trouble.

Janessa might have been betrayed by someone she trusted. Maybe a close friend spread false rumors about her at school or work. This would make her feel very hurt and sad, and she might start to question who she can really trust.
Loss. For example, a child losing their favorite toy. It might seem small but to the child, it's a big deal. The toy might have been with them through many happy times, and when it's lost, there's a sense of sadness.

It might be about the loss of a loved one. For example, if her grandparent passed away, she would be very sad. Grandparents are often a source of love and wisdom, and when they are gone, it leaves a big void in a girl's heart.
