THIS SONG IS IN CAPO 1. Or the key of F, if you're feeling adventurous. 

[Verse]
          E
I used to feel so strange
                 A                       
In my skin I was shaking
             E
I'd paint my room all black
                      A
And cover up all the walls
             E                             A
If you could rearrange what you saw in the mirror
              E
Well tell me 
                                           A
What would you change about the person you saw?

[Chorus]
    E
And honestly, honestly
            A
If you just promise me, promise me...
   E       A
To stay forever
C#m                 A
Never ever leave my side 
       C#m              B
If the sun never rose again 
    A
The moon will light the way, my friend
   E       A
So stay forever
C#m                     A
You're my only friend tonight
       C#m                  B
All we need is the shock of love
       A
In the dark
                E
We are electric hearts

[Verse 2] 
I use to feel so stuck 
In my head, I was breaking
I keep my secrets close
And never tell anyone
If you can dream all day
And coexist with living
My baby...
I'd dream of us and all the battles we've won

[Chorus]

[Bridge] 
C#m             G#m             A
    Life is the risk you take
C#m             G#m                 A
    Life is the love you make
C#m             G#m               B
    Love is the great escape

[Weird talking part]

[Chorus]
