They have always told me patience was virtue. I have been patient my entire life and I'm still waiting. I'm still here and I can't take this anymore. Why is this solitude so depressing.
- Freeze frame. I see where this is going already. Very ranty. Tread carefully, otherwise this will come off sounding juvenile.
I can feel the tear sliding down my cheek leaving me with an itching sensation of sadness.
- Too maudlin. I envision a sad clown with the single tear.
This time bomb is ticking down inside of me and the next person who gives me any shit, I swear will wish he had never messed with me.
- Cliche is plague. Already I can tell that you are too good of a writer to resort to using expressions like 'ticking time bomb'. And please don't kill me
I loathe and pity you... Jarod
- Why use an ellipses here?
All that I can do is stare at the darkness of the decadent walls.
- I thought they were white walls?
I am hardly insane, but he should not of done that.
- Of -> have
It could be saturday or maybe sunday or monday or tuesday, hell, I don't know anymore.
- Caps the days of the week and Hell.
I cry myself asleep again. Its all that I can do
- To sleep. It's, with the apostrophe. And cliche.
They always come by and stare into my window and stick the needles under my skin to make me sleep.
- The simplicity of this statement is kind of creepy. Well done.
Oh joy! I have so much fun, but no... they have done it again.
- This made me laugh out loud

I love gleeful murderers haha
I remember my highschool girlfriend, and her gentle touch. I remember the white walls and my friend Derick. I now realize something, it is already too late.
- In your last sentence, try changing the comma to a colon for effect. The ending is actually kind of creepy, too, but lacks originality in its delivery.
Overall thoughts about the piece. Typos and spelling errors brings the quality of the piece right down. You have some good creepy moments that nearly save this from sounding, well, juvenile and like you're just going through the motions of insanity. Insanity has been done time and time again, so it's important to do it in a different way. The writing is pretty good, though, so the piece was still fun to read, and that 'oh joy' line was pure gold!

Let's see some more.
Cheers,
