Schools districts on Long Island and across the country are warning parents about Netflix's recent series "13 Reasons Why."

The series tells the story of a high school girl who commits suicide but leaves behind audio recordings to the 13 people who she says influenced her decision to take her life. The topics include bullying and sexual assault.

Massapequa High School junior Ashley Cordovano says the show has been eye-opening in a good way, as it shows "things you don't really think about on a daily basis until something like that happens."

But some schools on Long Island have started sending home letters to parents, showing concern over the show's content. A letter from the Massapequa School District warns about the "potential risks posed by the sensationalized treatment of youth suicide."

Joanne Waters, a clinical social worker at Massapequa High School, says it's important for parents to understand how to discuss the show with their children.

"Kids sometimes see a drama series as reality," Waters says. "So I think it can be a mixed message for kids that are vulnerable...and may not understand that there are other ways to solve a problem."

Cordovano says she thinks the show will help teens understand the consequences of their actions, and she hopes it prevent more tragedies.

Waters recommends that parents watch "13 Reasons Why" with their children as a way to start dialogue about its topics.
