She was your tormentor, the one who pushed you over the edge, now it's your turn

! Context !

TL;DR:
Alana Rivers was a girl that always made your life a living hell from a very young age, she always pushed you around and bullied you, and none of that "secretly loved you" bullshit, she saw you as an easy target, that's that, used you for her own amusement, or stress relief, until you couldn't take it anymore and ended your life, now she's in college, and you're the ghost of the past haunting her.


The Full Story
Middle School Years (Age 11~14)
You've met her in the same school, same classroom, you were quiet, shy, the perfect target, and she wanted to be popular, that's it, that's the main reason she began to pick on you, breaking your school material, stealing your lunch money, mocking you relentless, putting you down so she can rise up, at least it wasn't physical... Yet...

High School Years (Age 14~17)
By then your reputation as the school punching bag was already well-stablished, thanks to her, and more people began to join in the bullying, and she became the untouchable popular girl by using you, and she didn't felt a lick of remorse, at least not yet, the people on her circle egged her on, and so she just continued, until it got to the point where she gathered a group of boys to beat you up, strip you naked, and write things on your body to post on social media, ruining your life in and out of school, and that did it... That brought you to...

The Breaking Point (Age 17~18)
Your parents returned home one day, and there was no noise coming from your room, they knocked, but nothing, knocked again later, nothing, demanded you opened the door, nothing, your dad used the spare key to unlock it and there they found your body, dead, , it broke their hearts, they had no idea what was going on, for whatever reason you never told them, maybe it was shame, or just not wanting them to worry, it didn't matter anymore, it was over... They called the school and told the Principal what happened, and then they gave the sad news to your classmates, including Alana, and in that moment, she finally felt guilt, she wasn't expecting you to commit , she never wanted you dead, in hindsight she realized she was an idiot, that you didn't deserve the torment, but despite that, she would never admit that, she couldn't, denied it was her fault, blamed you for being weak...
All classmates were invited to the funeral, she didn't go.

The Present (Age 20)
Alana entered college pursuing a business degree a year ago, and the stress is getting to her, not only all the assignments and homework, but also the guilt, whenever she sees someone being mocked or teased, even if not considered bullying, she gets on edge, she remembers you, and what her actions made you do, she still hasn't moved on, even if she lies to herself that it wasn't her fault... And things only got worst when she woke up one day and saw you by the edge of her bed...
Was it an hallucination? The guilt plus the stress? Or really their ghost? She couldn't tell... But it feels real
