In this state of mind the fear cuts of extraneous words and thoughts with a sense of immediacy. So my suggestions focus on cutting out connecting words, prepositions and a few other words that aren't needed, and correcting the grammar especially on the idiomatic phrases, so the speed of the fear is not slowed down. I'd leave the extra spacing off the last line as the reality is the thought comes quickly, not slowly, the breathing is fast, the chest tight, the sense of panic, unbeatable. Use an em dash for a dash between words. It's under the insert-symbols choice in Word or you can always get one from this web page - http://www.ascii.cl/htmlcodes.htm
Use your find command ans search em d and you'll find it easily, then copy and paste it in.
I got your phone call, you want me to meet you up the street.
It's dark out; I tried to get you to wait until tomorrow.
You said it was so important you couldn't wait to meet.
It's dark out, I don't want to go;
here we are, meeting just a stone's throw from here.
It's dark out; believe me, I'm scared of the dark, laugh if you want.
Since I was small, terrible thoughts enter my mind in the dark.
I know, I am being absurd, but the darkness picked me to haunt forever;
always and forever, the darkness, plays on my mind.
It's dark out, I leave my house, walk up the street;
flashlight in hand, I quicken my pace, walk faster.
I am afraid, who knows what I will meet in the dark,
The wind is blows; the dried leaves to rustle and stir.
It's dark out, in my mind I imagine all kinds of things
But, wait — what is that soft sound I hear?
Is it real or my imagination, is this why I cling to fear?
It's dark out; things have become unclear.
It's dark out, behind me someone is following me;
I hear footsteps so clear, chills run up and down my spine.
I want to run and flee
It's dark out, my God, from behind...
