I've been searching for a Dramione fanfiction for a very long time and haven't been able to remember the name.
The general outline of the story follows a severely depressed Hermione following the end of the second wizarding war. Before she is due to go back to school to complete her education she uses the cruciatus curse on herself, visibly damaging herself as well as mentally.
On her return to school she is allowed to live in her own accommodation which happens to be above Flourish and Blotts where she works part time as well to cover her rent.
On returning to school there is a new Defense teacher who takes a different approach to teaching the students returning following the war. The class includes Zabini, Ginny and Draco. Upon finding out about Hermione's self torture, the teacher creates a potion for her which the other students bring to her daily at her appartment to make sure she takes it, this is where friendships start to blossom.
This fanfic also includes a dark Harry, but it is the Hermione part of the story that I remember with more detail, if anybody has read this story and knows the name of it I would be so grateful.
