[Serious] What's happening with Hana Kimura?

Her recent tweets are incredibly alarming, showing graphic images of self-harm and implying she intends on commiting suicide.

EDIT: A string of tweets from the last 15 minutes roughly translated (I ask that no one posts the links to the self-harm images.)

"Nearly 100 frank opinions every day. I couldn't deny that I was hurt. I'm dead. Thank you for giving me a mother. It was a life I wanted to be loved. Thank you to everyone who supported me. I love it. I'm weak, I'm sorry."

"I don't want to be a human anymore."

"It was a life I wanted to be loved."

"Thank you everyone, I love you."

"Bye."

EDIT 2: The tweets are deleted now. Not sure if she was hacked or what.

EDIT 3: It has been confirmed by Stardom that Hana Kimura has passed away. May she rest in peace.
