As someone who has struggled with bouts of depression, I can tell you one big reason to avoid 13 Reasons Why.
Hannah's reason for suicide was mostly based on vengeance. People don't commit suicide because they're angry. They commit suicide because they are so utterly lost, helpless, and isolated. It it a decent novel? Sure! But not an accurate one.
I mostly say this because of some media hype surrounding the Netflix adaptation. I've already come across embarrassingly inaccurate articles about how Hannah could be compared to teens today, and a bunch of other hogwash.
