"There is a great concern that I have ... that young people are going to overidentify with Hannah in the series and we actually may see more suicides as a result of this television series," said Dan Reidenberg, the executive director for Suicide Awareness Voices of Education, a nonprofit group with the mission of suicide prevention.
"I've heard from others that are really concerned because its so sensational and so graphic that they're worried about the copycat effect of suicide," he added.
Suicide is the second leading cause of death among those ages 15 to 34, according to the U.S. Centers for Disease Control and Prevention.
"The way things are portrayed in the media does have an effect on the way suicides can happen. This is particularly true for young people that are very vulnerable and at risk of suicide," Reidenberg said. "When they're exposed to images that are really graphic, really sensational, and there is nothing balancing out for them ... that they can get help and that treatment works and recovery is possible ... we see them actually replaying what they've seen."
"The show actually doesn't present a viable alternative to suicide. The show doesn't talk about mental illness or depression, doesn't name those words," he added. "My thoughts about the series are that its probably done more harm than any good."
SAVE partnered with another suicide prevention group, the Jed Foundation, to provide tips for viewing "13 Reasons Why" and talking points for parents and teachers discussing suicide with young people.
Child psychologist Janet Taylor said she applauds Gomez for addressing mental health issues on the show.
"We have to break the silence, talk to our parents, talk to counselors," she added. "If you have a family history of mental illness, be aware of it, talk to your children. If your child makes a threat about wanting to hurt themselves, take it seriously."
Producers for the show said they hope the series can help those who may be struggling with thoughts of suicide.
"We wanted to do it in a way where it was honest, and we wanted to make something that can, hopefully, help people, because suicide should never, ever be an option," Gomez said in "Beyond the Reasons," a video released by Netflix to accompany the series.
Co-producer Brian Yorkey added that the show's creators "worked very hard not to be gratuitous, but we did want it to be painful to watch, because we wanted it to be very clear that there is nothing, in any way, worthwhile about suicide."
Jay Asher, the author of the book "13 Reasons Why," said, "Suicide is an uncomfortable thing to talk about, but it happens, and so we have to talk about it."
"It's dangerous not to talk about it, because there is always room for help," he added in "Beyond the Reasons."
Members of the production team said they consulted with mental health professionals extensively while making the series and provide suicide prevention resources and information on crisis hotlines in more than 35 countries on the website 13ReasonsWhy.info.
Daniel Feinberg, a television critic for The Hollywood Reporter, told ABC News that the show definitely "demands conversation."
"The show is about how if we don't treat each other better, if we don't have conversations, if we don't communicate, horrible things happen," he said. "People end up feeling alone, and people end up feeling hurt, and then when people feel alone and hurt, that's when they do things like this."
