Save me ~ Levi x Depressed! Reader

This is a story about you! (obviously) and this is your backstory!! :P
WARNING: Highschool AU not original plot. :)
OTHER WARNING: Self-harm, violence ( probably ) and maybe a lemon if you're lucky ;)

(Y/N) Lived with her mother and father most of her life, they would abuse her and things like that, until one day at the age of 10 she had had enough, so she grabbed a kitchen knife and..... I'll spare you the details, basically, she killed them.
After that she called her grandfather and told him what she did, to which he completely understood and called the police, explaining the situation.
In her life, (Y/N) Never had any friends as she was depressed and had serious social anxiety, and anxiety in general, now that she's in highschool in her second year and she meets some interesting people.
