Trapped In Your Mind

Skylar was a normal girl, she made good grades, came home on time, used her manners.
Once she went to high school that all changed, Skylar met Sebastian. Sebastian showed Skylar all the "good" things in life, like parties and drugs, all that good stuff.
One day Sebastian comes home blood splattered. Skylar didn't question him on it.
Its been a year since Sebastian was taken away for mental help after killing someone.
Skylar had gotten worse and worse with each day, drinking, smoking, cutting, she didn't want to live anymore. So she decided not too; but that just landed her in the hospital.
Skylar meets a boy while she's there, someone who makes her realize all the good things in life, someone who she didn't know could exist.

Skylar learns that there's two sides to everyone she meets.

What if Sebastian came back? What if he found Skylar?
