"When you feel so tired but you can't sleep, stuck in reverse"; how can I change my life?

I’m a 16 year old girl and do you know the words “When you feel so tired but you can’t sleep, stuck in reverse“ in the song “Fix You”? The point is, I’m like that. My mom doesn’t understand, my step-father is often not home. I hate to go to school, I’m scared, and i don’t want to face the things in school. I want to run away, but never try, because I know going to school is the best way to my dreams. I want stay alone, but I don’t want to feel lonely. I want to see the sea, I’m born to find hope, I immerse myself in rock’n’roll, I have a best friend, just like me, I hope we’ll be happy.
