...what has happened?

In my life everything seems like its going so fast. Next year ill be going into a new school. My sister is getting married. The boy that i thought i loved is going to a different school and i cant take all the changes that are happening all of a sudden... i miss the days were nothing ever changed, where all i had to worry about was looking nice for my crush or just doing my homework... but now everything is hitting me like lighting and i dont have any control over any of this. Some times i wish everything would just freeze so i can just take a breather or something. All of the people ive known for more than 5 years are leaving to different places and schools. My best friend, my sister, is now getting married. Im not her only priority anymore, shes going to go get married, eventually have kids, and have a full, complete life, while ill just be a minor detail to the story. Sometimes i hate being at home, i feel that my parents expect to much from be, to live a outstanding childhood like my sister, but im not capable of that. Im a different person, im not as smart, athletic, family orientated as her. im the black sheep. even though people see me just as the youngest, the one who is in the background smiling, they dont see what really happens behind the scenes or behind the smile, what my life is really like, because they dont understand...
