Mistake ~Draco X OC

Story Description
Alexa Adams is born from muggle parents, who don't even acknowledge her existence. Her little sister is their pride and joy who can't do anything wrong. Alexa on the other hand can't do anything right in their eyes, causing her to be turned into a personal punching bag to let out their anger. Alexa has tried fighting back, but it always ends with her being even more hurt. This has turned Alexa to never show her emotions and most people view her as a cold-hearted bitch.
One day a letter shows up addressed to her from Hogwarts School Of Witchcraft And Wizardry. Her parents almost instantaneously decide to send her, and pay for anything she may need, saying "at least she can screw up someone else's life not ours". When getting to Hogwarts she is sorted into Slytherin, but muggle-borns aren't even put in Slytherin. Her whole house ignores her and is always pushing her around. Alexa feels exactly as she did at home, and decides to finally stand up to constant bullying. She gets in so much trouble, even more when the person she has stood up to is the pureblood Draco Malfoy.

Quick Note: With muggle-born witches and wizards the letter is delivered by a member of the Hogwarts staff. This is to explain everything to the family.

There are some triggering things is this story such as mentions of :
Self-harm
Suicide
Ect.

There is also strong language. This story also starts with the first Harry Potter book/movie. It will not follow the polt exactly as it is from my OC's point of view.

I DO NOT OWN ANY OF THE HARRY POTTER CHARACTERS
