Seventeen and Pregnant

My name is Lexi and I always have a way of screwing things up.
I just graduated high School in the summer.
It is now fall and I am six months pregnant....
To someone who is my best friend.
I am seventeen....
My best friends are in a band they call themselves Avenged Sevenfold.
I have vowed to be a better mother then my mother...
So what do I do when my world comes crashing down before it builds back up again???
