Maybe its her way of telling her 'friends'. She wants people to console her.

I suppose in the olden days people used to just cry and all your friends would be next to you to console you. But now all your friends on your phone. Instead of DMing them individually about how your brother shot himself she has resorted to this. A more rational way would have been Insta stories to close friends imo.

We cant 'fix' anything. This is how the world is.
