It's pretty easy, I'm not sure if it's 100% right but it's something :D 
Capo on 3rd

Em              C            G       D
You're way too young to be broken
Em              C            G       D
You're way too young to fall apart
Em              C            G       D
You're way too young to play these games
              Em      C
But you better start
                G      D
But you better start
(*it continues on like that for the rest of the song)


This is when it starts
From the beating of your heart to the street lamps talk to you
Jumping off of the edge or asleep in your head
Everything's turning dark to you
I went to pick the up the parts
The doctors hiding the charts
He won't let me see this side of you
It's on the tip of my tongue You know you're way too young to have someone 
lie to you

((CHORUS))
             Em
I'm not the one
             C                 G        D
I'm not the one who wants to hurt you
             Em
I'm not the one
             C                G        D
I'm not the one who wants to hurt you
             Em            C            G            D
You better find somebody else to get a hold of yourself
             Em
I'm not the one
             C                G       D
I'm not the one who wants to hurt you


You're way too young to be broken
You're way too young to fall apart
You're way too young to play these games
But you better start
But you better start

It was the second I lit
Your first cigarette
I forget who you used to be
And I bit my lip
The second you sipped, the poison that was mixed for me

((CHORUS))

Drink the poison lightly
Cuz' there are deeper and darker things than you
I know, cuz' I've been there too
I know it might seem frightening
To have the world fall apart right under your shoes
Trust me, you'll make it through

((CHORUS))

ENJOY!!!
