Can you really change a Prophecy?

mortem (short)

It was almost midnight when you made it back to the common room. No one was awake which was good for you, you were extremely exhausted. You walked into your room and there was someone lying in your bed, you pulled your wand out ready to fight. "No, it's just me," Draco's voice filled the silent room. You lowered your wand a bit, but not fully putting it away. "Get out," You said softly, Draco looked up at you with confusion. "I didn't stutter, get out." You said more clearly this time. "Why are you mad at me? What did I do this time? I haven't done a thing, I'll tell you." He said angrily, getting up and moving towards the door. "You haven't done anything? Well Malfoy, what about the rumors? Huh? Don't act stupid, you know exactly what you and Pansy did." Draco looked at you with sadness in his eyes, "I haven't said anything," "Yeah, right. Then who spread the rumor about us apparently dating, and the fact when you came in to save me you had found out I was trying to kill myself and since I was sooo Psychotic you decided to break up with me." You paused, catching your breath, "You're the psychotic one, and we will never, ever be together." Draco looked at you with pleading eyes that suddenly changed into anger. "Fine, be that way. I didn't start anything," "You didn't start anything? You started everything!" You interrupted him. "I'm going to write to my mother and father, asking them and pleading with them to ask the dark lord for me to be alone, or with someone who doesn't want to destroy me as much as I want to destroy myself." You yelled at him, when you finished Draco came after you grabbing your shoulders. "I don't want to destroy-" in an instance he was on the floor writhing in pain. "Don't touch me ever again, Malfoy." You said before stopping. You had silently casted a Crucio curse on Draco, your first one ever. "Get out of my room, and don't ever talk to me again." He nodded his head, and left.

The Yule ball was a few days away, and it has been weeks since you last associated with your group, well they were no longer your group. None of them looked at you or even tried to talk to you. Which was perfectly fine with you, you had grown to being all by yourself, doing nothing but staring at your ceiling until it was time to get up for class. You haven't slept or ate in days, however, you had been excelling quite greatly in your classes. You also go and see Dumbledore quite a lot, he just sits there and listens. It was all just going by slowly and crushingly. Your mind and soul was hurting, and it was destroying your body from the inside out.
