Shattered - A Miraculous Ladybug fanfic

This is a Miraculous Ladybug fanfiction taking place after season 4.
WARNINGS for death, anxiety, suicidal tendencies, and grief. (Most are depicted in a light manner, but they are present in the story.)

First Gabriel's secret, then Adrien's. Marinette is devastated to the point where she can't think clearly and has to be taken away from a battle by her partner so they wouldn't lose. Luka is just the icing on the cake, although it pushes Marinette toward the brink.
Knowing what she knows, Shadow moth threatens her to be akumatized, resulting in devastation. No one knows how to help Marinette, and no one can beat her if she wants to save the one she loves. She learns way too late why secrets need to be shared early on.
When her dreams and future are shattered, will she be able to resist the temptation of revenge? Or will she give in to her hatred and anger?
