Why did she die?

I liked Goshai-chan.

Videos on her channel are not updated.
There are many voices of sadness in the comment section of old videos.

She have confessed that she have bipolar disorder and that when she is depressed, her mental health really breaks down and she can't even put on makeup or take a bath.

She created 'Jirai-mori line', published a book, and even had her own brand, 'Armuje'. She also went on a trip to Paris with her boyfriend.
Even after the news of her death, Goshai-chan's autograph was still displayed at the color contact counter in Shibuya, which made me feel a bit awkward. People simply disappear.

A brilliant achievement achieved by a 24-year-old girl while attending university. There's no way to know what was bothering her behind the scenes.
Was she a self-disciplined person who tried to do her best to meet the expectations of those around her, or was she having trouble with relationships, or was she hurt by anti-comments on social media?

I'm so sad.
I wanted to support her straight away.
