Behind the curtains

Feel like on the scene. But I'm not plaing, I'm just watching it.
Watching a girl, who looks just like me, but not acting like me. That's not who I am!
I just want to step out and scream "I'm not that way!"
But I couldn't...That curtains not letting me go there. I'm trapped. In me. In my deep soul...
That girl is better for someone, but not for closest people.
I want to kill her stupborn and selfish character. I want to ask her why does she doing this, that's not who we are! That's not the way
But I couldn't. She locked me in curtains. And I don't know if I could ever get out. Dissapear...
