Book Of Stupidity

Disease of the Mind (Part 1)

Just a warning, it's about to get serious. Not joking. Get ready for some edgy shit these next two chapters.

V's POV

What's happening? Out in the woods I was so... angry. I shouldn't be surprised, though. I'll always get mad at my siblings now and then. But... this time... was different.
I heard voices... saying,

"She hates you. She doesn't love you. Destroy her, V."

I couldn't kill my sister! Yeah, I wanna strangle her every now and then, but she's still my family. I sat on my bed, burying my face in my hands.
The amount of damage I caused over a small argument with Onee-chan almost scared me. How strong am I? How angry can I get? A part of me said, "Fix it with your sister," while the other said, "Kill her."

Am I finally losing my mind? Was the rest of my sanity slipping away after so long?

"What do I do?" I muttered to myself.

I tried to think reasonably, but my mind was too foggy. I couldn't think straight. I looked at my scratching wall. I gazed at all the scratches my cat claws made when I got angry at Shadow or the others. I placed my finger tips as high as I could reach, and suddenly raked them down hard, making new marks on the wall with a SCRREEECCCHH.
I heard a knock on the door, making me jump a little. Quickly, I covered the wall, and went to see who it was. MoonPie.

"Kon'chiwa, MoonPie-chan."

"Hey V," she said, "Everything okay? You seem... on-edge."

"It's nothing, cous," I smiled, "I'm fine. Thanks."

"You sure?"

"Yeah. Just a little steamed still."

"Okay," she smiled slightly, "Just checking. Hey, Yuki and I are gonna binge YouTube. Wanna join?"

"Sure," I replied, "Sounds fun."

She beckoned me to follow her, and I complied. We binged out on Markiplier, Yammimash, Jackcepticeye, etc. I enjoyed laughing, and making commentary on all the gaming, mistakes, and the YouTube-ers' getting frustrated or scared with Yuki and MoonPie.
But the mental incident still lingered in my mind. Eventually, I blanked out, and drifted into my own thoughts. Where did this darker side of me come from? What can I do to stop it?... Will I end up killing one of my own friends?
What am I becoming...?
Suddenly, everything went black. I was in a dark room, with nothing but a mirror. I walked up to it, and saw myself.
But it wasn't me.
The reflection's hair was midnight black, her skin was paler than mine, and her eyes were black holes with iridescent teal centers. The corners of her mouth were cut to look like Jeff the Killer, except razor like teeth jutted out, stopping at her actual lips. Curious and skeptical, I did a few hand motions, and the reflection seemed to follow them correctly.

"What are you?" I asked in a whisper.

It smiled and spoke in a distorted voice, "You could say I'm the... darker side of you."

It then stepped out of the mirror, and was inches from my face.

"You can't," it whispered before vanishing.

What did that mean? What can't I do?! I then heard someone calling my name in an echo, getting louder and louder.

"V-CHAN!!!"
