Have you heard the legend of Darth Sayori the Depressed?
I thought not. It's not a story the Anti-Bully squad would tell you. It's a Literature Club legend. Darth Sayori was a Dark Lady of the Literature Club, so cheerful and loving she could use her positive attitude to calm arguments... She had such a knowledge of charisma, she could even keep the ones she cared about from depression.
She become so depressed... the only thing she was afraid of was losing her lover, which eventually, of course, she did. Unfortunately, her lover rejected her on the spot, and she hanged herself. Ironic. She could save others from depression, but not herself.
