Not 100% accurate but in my opinion better than the very few tabs out here. In this
intro the strumming pattern "weaker" than during the song, try to make this a little softer
so that even when making the same chord you get a slightly different impact, this can be 
done by in the intro strumming mainly the B and G strings. Listen to the song over and
over to the understand the patterns, riffs, everything

riff 1:
-0---000---0----0------| e
-1---111---1----1/3----| B
-0h2-220h2-2----2/4----| G
-0---000---0----0------| D
-----------------------| A
-----------------------| E

Am/D (xx0120)

Let's call riff2 to the riff 1 without the slide of the chord. The transition from riff1 to Am/D

Intro: riff1 riff2 riff1 riff2    riff2+Am/D

Am/D                             riff2 Am/D
I was thrown out from your world
                                 riff2 Am/D
I just got out by your back door
                                 riff2 Am/D
Suddenly my brightness became so bored
                             riff2 Am/D
Maybe I just can't bright anymore

Am/D                           riff2 Am/D
Yes I am ugly as much as I can be
                                   riff2 Am/D
and, that was always a big part of me
                                   riff2 Am/D
you're dragging me down for what I am
                           riff 2
Maybe I never was what you planned


C            G
Soon I'll be dead
                 Bm
My words in your head
              G      Gm
Will now be a shadow
D      G            Gm
All my feelings are broken
D         G       Gm
Love just can't be spoken

Same as Verse:
When was the last time your eyes saw me ?
I don't remember, was I on my sleep ?
You're dragging me down for what I am
Maybe I never was what you planned

Same as Chorus
Soon I'll be dead
My words in your head
Will now be a shadow
All my feelings are broken
Love just can't be spoken
No using pretending sorrow
Where will I be tomorrow ?
