Worried about ’13 Reasons Why?’ Mental health experts are here to help.

The new season of 13 Reasons Why picks up where the show's debut left off and tries to tackle several painful subjects, including suicide, depression, bullying, sexual assault, and the threat of school violence.

That's intense content even for adult viewers. But for adolescents and teens, particularly those who've already endured some type of trauma, these storylines can feel all too real.

A new toolkit created by dozens of mental health experts is designed to help anyone who encounters the show — either by watching or hearing about it — deal with its potentially traumatizing plots and themes.

The toolkit contains different resources and guidelines for youth, parents, educators, clinicians, and the media, and its goal is to encourage positive conversation about the show's content, help bystanders identify young people at risk of mental health crises, and provide resources for support and professional care.

When the show launched last year, it received praise for its willingness to take on taboo experiences as well as criticism for its graphic portrayal of suicide and sexual assault. At the time, Netflix hadn't included detailed content warnings or mental health resources in each episode, nor did it consult with national mental health experts.

"Last year, no one was really prepared for what the content was going to be," said Dan Reidenberg, executive director of Suicide Awareness Voices of Education, a nonprofit organization.

This year, Netflix is offering its own collection of resources, including a discussion series with cast members, a website that lists mental health organizations, and a downloadable discussion guide. The second season opens with an extended content warning, and each episode ends with contact information for those seeking help.

Reidenberg, who led the effort to develop the independent toolkit, said that he'd communicated with Netflix about the second season's storylines but didn't have early access to the episodes themselves. He said the toolkit may evolve to incorporate new resources depending on how the season unfolds.

To create the toolkit, Reidenberg helped bring together 75 experts who work in suicide prevention, education, and healthcare around the world. He described the effort as "precedent setting."

The toolkit includes guidelines for how young people can take care of themselves if they feel affected by the show, and how they can spot warning signs in friends and loved ones.

Among the toolkit's recommendations are that "vulnerable and at-risk youth" should avoid watching the show; parents should try to view it with their children; educators should ensure that parents and caregivers know the second season is now streaming; and mental health professionals should consider watching the series to prepare themselves for conversations with clients who've seen it.

While Netflix has been responsive to critics, it's not clear the show handles sensitive storylines as responsibly as it could.

One particular aspect of the new season that concerns Reidenberg is the continued presence of Hannah Baker, who previously died by suicide. That she appears in flashbacks and in one character's hallucinations may be confusing to some young viewers, suggesting that even if you've died by suicide, you can still somehow play a role in people's lives.

"It does increase the risk that young people who see this and are at risk [of suicide] may believe they can do that too," said Reidenberg.

Still, Reidenberg is hopeful that the toolkit will help young people and the adults who support them discuss the show in productive ways: "We really wanted people to be prepared this year."
