Mistake (A sad one shot), chapter 1

As I sat on the cold bathroom floor, the screams and crashes wafting through the vents from the lower levels of the house, I thought about what I did wrong to deserve this.
As I lay in this pool of crimson color, I think about what I did for everyone to hate me so much.
Nothing comes to mind. I shiver as another gust blows in from the open window.
I look at the piece of bloody glass laying next to me, seeing how the color drains from my face. It seems as if I don't feel a thing.
I feel another wave of pain rip through my arms.
I guess I can feel it.
The screams die down for a short moment, then come back full force.
I know they are yelling about me.
About how much they hate me, and how much at fault the other was.
I was always called the mistake.
I guess I really never had a name at home. It was always Mistake. For thats all I was.
I feel wet pricks on my face, and look at the open window again to discover it was raining out.
Rain was always the best thing to ever happen to me. I could go out and sit, letting the falling water wash away my troubles, but they would always come back when I was done.
I note that I stop feeling pain, but instead feel a prickling sensation through my body, mostly at my arms.
I blink slowly, and looked at the destroyed bathroom. This was my parents parting gift. To wreak havoc one last time before I was gone forever.
But they wouldn't miss me.
They would probably party.
I don't think anyone would miss me.
I felt another gust of wind, and discovered the rain had turned to snow.
I never liked snow. My mother would always lock me out when it snowed, just to see me-
Shit.
I hear her footsteps. I suppose she is coming to throw me outside.
I bet she will laugh at me.
Laying on the floor, in my own blood, bloody glass all around me, destroyed bathroom, and water everywhere, she will scream, then laugh at me as I die.
She opened the door and screamed, as expected, then shook her head sadly, thinking about her bathroom, and walked out.
I weakly smirked at this and then felt my eyes close, then I shot them open again.
I knew what was coming.
I've done this before.
Suicide.
I didn't succeed last time. My parents caught me.
But this time, I made enough cuts to ensure I will not live.
It doesn't hurt. I made careful not to miss the vein, or I would fail again ,but I didn't.
It's harder to breath now, it's a struggle.
My eyes close again, but I tried to keep them open.
I want to see thier satisfaction before I breath for that last time.
I hear more footsteps and the door opens, and I see both my parents in the doorway, staring on with horror.
I manage to choke out;
"I would...be sorry about..your bathroom..but I liked to...think..of it as payback.." I coughed and felt a metallic taste in my mouth, and then my eyes drooped again.
My mother was crying.
"Cecilia...Stop..crying..it doesn't..suit you..." I whispered and she wiped her face, and I coughed again, more blood exiting my body.
"My last words..." I said and looked at them.
"F-fuck you.."
I felt immensely cold, and then I found I couldn't breath anymore.
My eyes would not stay open anymore, and shut fully.
The last thing I heard was my mother sobbing, and my dad punching the wall.
Goodbye World.
