Twinning

I was an orphan for 15 years of my life. I didn't realize that fainting and being hospitalized would be the best thing that ever happened and the start of the worst. When I was born I was separated from my birth parents. So the doctor sold me to this orphanage where I have been for the past 15 years. I've seen people come and go. Including people who were my best friends and enemies. One of my so called "best friend" stole the people who were going to adopt me and instead she went home with them. Now I'm with my family and it turns out I have a twin sister who is literally my best friend. One month after they took me home with them, she was kidnapped!
