Big Mistake. Or Not? ( Chocago P.D Fanfic)

A nightmare from past

"Run!" a very familiar voice can be heard from behind me
"Run!" I run very fast but I can feel that they right behind me.
"Don't turn around. Run. They will catch you!" I decided to turn around. I saw Hailey running behind me. We ran into a building and hide in there. 
"Hailey, I'm scared." I say.
"Shh! They can hear you." Hailey said to me. She hugged me.
"What if they catch us?" I ask Hailey.
"They don't." she said.

We were sitting on the ground when we heard footsteps. I was breathing loudly so I cover my mouth with my hand. The footsteps was right behind the wall we were sitting next to. Tears began to fill in my eyes. Hailey hide me behind the steps when the Police catches her.
"Where is your sister?" one of Policemen's asked.
"I don't know what are you talking about." Hailey said.
"Don't act like you have no idea what we talking about. I ask one more time. Where is she? Where is your sister hiding?" the Policeman shouted at her.
"I don't know. I didn't see her since we ran away from house."
"Search everything in here. She should be somewhere here." the Policeman said to his partners. "And you come with me." his said to my sister and took her with him. I was sitting there for almost hree hours when Policemen finally drove away. I left the building and started to walk around the city to find a way to home.

I finally find my house. I entered it.
"Mommy?" I shouted but no one is answers. I went upstairs and in my sister room but she was not there. Then I went to my parents room. And no one was there to. I went downstairs and in the kitchen. I took some food because I was hungry. I sat at couch and started to eat when I heard that someone is rang in doorbell. I went to see who is this. I open the door. It was a Policeman.
"This is where you are. C'mon you're coming with me." his said to me and took me into his car. We drove to the Police department. The Policeman lead me to the room where I saw my sister.
" Hailey!" I shouted and ran to her and hug her.
"Cris!" she hugged me too.
"Okay. Yours mom is gonna be here in two hours." the Policeman said.

Two hours passed and our mother finally entered the room.
" Mommy!" I shouted and i and Hailey ran and hug her.
"My little girls." She hug us. A few minutes later we drove home where we met our dad.
"Dad?  What are you doing here?" Hailey asked him.
"Hey sweeties." his said to us with smile.
"Hailey, Cristal. Me and your dad have yo say you something." mom said with tears in her eyes.
"Mommy? What happening?" I ask her.
"Girls... Me and your daddy..." she didn't want to say it but she have to. "Me and your dad is not together anymore... so..." she said and tears is fell down her cheek.
"Mom?" Hailey says shocking.
"Your mom want to say that one of you is gonna stay with me and other is gonna stay with your mom." Dad said.
"What? No! I'm not gonna leave my sister!" Hailey shouted with tears in her eyes.
"I know sweetheart but you have to. I'm so sorry. I can't do anything with this." Mom said.
"And who is going with dad?" Hailey ask. Mom started to cry.
"It's Cris." Dad said.
"No! You can't take her! You can't!" Hailey started to cry.
"What happening? Mom? Is this mean that I can't see Hailey anymore?" I ask getting closer to Hailey.
"C'mon Cristal. We have to drive to airport." My dad said and took me to his car.
"No! Mommy! No!" I shouted crying.
"Cris!" Hailey said crying to.
"No! Nooo!"

I woke up in a cold sweat. I look at the clock. It was middle of the night. I got up and went to the kitchen. I took water and sat and the chair next to table. It was third night when I can't sleep because of nightmares. I live in Chicago for week now. Tomorrow I'm going to search for work. I sat there for re minutes. My dog run to me.
"Hey buddy. I'm okay. Love you." My dog West is always here in bad times. His one, who always here for me and who supports me. After an hour I went to bed and tried to sleep.
