Just because something happens to a lot of women doesn't mean that it's ok.
She sure needed attention. Her parents couldn't give her time, her friend had moved, she was in a new city, she needed friends to talk to and what not.
Women think a lot, like a hell lot, and they just need to get things out of themselves sometimes. Men have testosterone, and so when they are hurt they harm others( Tyler Down) and women think and react, so they hurt themselves and blame themselves for all mistakes(Hannah Baker). Every women needs attention(although the type of attention is different for everyone) and Hannah wasn't any different is asking that. She wanted to be heard, she wanted to speak it out loud enough to reach every single person, and she did, by those tapes.
Learning that the world is evil is one thing and learning and dying with it is another thing. Just because you know that a test is difficult doesn't mean you drop it even before starting it. But you have teachers to tutor you, parents to give moral support and friends that say,"Dude we will do it, worry not." She had none. Now there was miscommunication from her end as well, but there is just so much that you can expect from a person who has been raped and saw her friend get raped.
