Hi everyone!
This is my first tab so be nice :)
I was looking at the other tabs for this song and even the ones with 5* didn't sound accurate at 
all so I did this by ear and I thinks it's better.
I personally prefer to play this on my electric guitar but it sounds good on acoustic too!
I hope it's good + enjoy!

Standard tuning. 
No capo.

(Intro)
Abm (Abm) B F#

(Verse)
    Abm
Insecure
      (Abm)
In her skin
       B                   F#
Like a puppet, a girl on a string

       Abm
Broke away
           F#
Learned to fly
       B                    F#
If you want her back, gotta let her shine

(Refrain)
      Abm                     (Abm)
So it looks like the joke's on you
           F#                        (F#)(once)
'Cause the girl that you thought you knew

(Chorus)
         Abm  (Abm)
She's so gone
          B    F#
That's so over now
         Abm  Abm
She's so gone
          B        F#
You won't find her around
        Abm     (Abm)
You can look but you won't see
    B     (B)
The girl I used to be
       F#    (Stop)
'Cause she's
         Abm  (Abm)  B  F#(once)
She's so gone

(Verse)
       Abm
Here I am
       (Abm)
This is me
        B                      F#
And I'm stronger than you ever thought I'd be
        Abm
Are you shocked?
        F#
Are you mad?
                    B            F#
That you're missing out on who I really am

(Refrain)
      Abm                     (Abm)
So it looks like the joke's on you
           F#                        (F#)(once)
'Cause the girl that you thought you knew

(Chorus)
         Abm  (Abm)
She's so gone
          B    F#
That's so over now
         Abm  Abm
She's so gone
          B        F#
You won't find her around

You can look but you won't see
    B     (B)
The girl I used to be
       F#    (F#)
'Cause she's
         Abm  (Abm)  
She's so gone, away
     B    F#
Like history
         Abm
She's so gone
      B       F#
Baby, this is me, yeah
