Sick Inside

And now I’m sick inside, yeah it makes me want to cry

I’m so sorry about last night

Yeah it happened so fast, I wanted it to last

In the moment it felt so right

But now I’m sick inside

Sick Inside - Hope Partlow

I pace around my room, crying. My actions were wrong but I lost control in a second and I did something I never should have done. Yes, I, Casey McDonald, kissed my step-brother Derek Venturi. Derek Venturi, who loves his girlfriend Sally. I replay last night in my head and feel horrible.

Derek was still at home waiting until he had to pick Sally up at 7:30. I followed him to the car and he turned and I saw how amazing he looked. My breath caught as I walked closer to him. When I felt his lips against mine I thought I would melt. It felt so right that I didn’t want to stop. We remembered Sally within seconds and pulled away from each other. I ran into the house and left Derek standing there. I ran to my room and felt shame at the fact that I had enjoyed the kiss. It was wrong and I had betrayed my friend Sally. I felt like crying all over again when I thought of Derek. He cared so deeply about Sally and I was sure he loved her. I had possibly ruined their relationship and Derek would hate me. I knew it was wrong to kiss your friend’s boyfriend and it was worse when he was your stepbrother. I cried until I fell asleep.

It was wrong, I tell myself. I wish I could make it up to Sally. I can’t face her. I can’t tell her that I care about her boyfriend so much that I feel sick today. But because I’m Casey I have to tell Sally. She trusted me and I let her down. I walk down the stairs and beg George to let me use his car for an hour.

"George, it's important, it really is," I plead. Eventually he gives in and I drive to Smelly Nellies.

I ask for Sally and the manager tells me to wait until her break in five minutes. I sit at a table and wonder what to say. Do I tell her that I kissed Derek first, or do I tell her that it was the biggest mistake of my life before I tell her that I kissed her boyfriend?

When Derek, who is working tonight, spots me. I watch as he realizes what I’m doing here. His face pales when he looks over at me, pleading me to just go home and not talk to Sally or tell her of last night's events. The look on his face almost makes me rise to leave, he looks unbearably sad, but my stomach squeezes and I know I have to stay. Sally deserves to know the truth.

Once Sally is on break she walks over to my table; her manager must have told her that I wanted to speak with her. After a deep breath I begin. "Sally, I have to tell you something about last night." When Sally looks puzled I continue, "I know you don't want to hear it either but I could never forgive myself if I didn't tell you what happened last night." Sally still looks confused but I tell her the rest of the story as well.

Sally stares at me in disbelief. Hurt and sadness are the emotions obvious from her expression. Stiil crying, I tell her that Derek obviously doesn’t want her to know because he doesn’t want to hurt her, or he would have told her himself. I listen to myself tell her that it’s my fault and that Derek really does love her. I end by saying: “I’m just a girl who kissed a boy who, is in love with you.”

So what did you think? Please review. I KNOW it could have been done better, much better. And please be honest, I want to know what you really think, not what you want to say to make me feel good about my writing because I value honestly above all else.
