Skylar Grey - Invisible chords

Capo 3.

Basically, the verses are all pretty much the same. C Em Am F

The choruses, I kinda modified it myself to sound better and not so mundane. where 
you can play them as:

C* 032010 Em* 020003 Am* 002213 F would be the normal F; but you can also still 
play the chorus with the normal C Em Am F.

And the pattern repeats. 

[Verse 1]

C                  Em
I take these pills  to make me thin

Am             F
I dye my hair,   and cut my skin

C                  Em
I tried everything, to make them see me
[ Tab from: http://www.guitaretab.com/s/skylar-grey/281407.html ]
Am               F
But all they see, is someone that’s not me

[Chorus]

C*
Even when I’m walking on a wire

Em*
Even when I set myself on fire

Am*                            F
Why do I always feel invisible,  invisible
C*
Everyday I try to lock my past
Em*
Even though inside I’m such a mess
Am*                            F
Why do I always feel invisible,  invisible

[Verse 2]
C           Em
Here inside, my quiet heart
Am              F
You cannot hear, my cries for help
I tried everything, to make them see me
But every one, sees what I can’t be
