The intro is pretty much just spazzing out on the higher strings in Em. Listen to 
the song if you want to get the timing and muting/harmonics right. 
Em                      C 
Bad things happen everyday.
G                      D 
Cancer and murder and herpes and AIDS.
Em        C    G        D 
We'll all die alone someday,
  Em            D     Em
I hope we don't die alone.

        Em                       C
And our vices make it bearable enough,
   G                               D   
To know our lives are shit, but to not give a fuck.
     Em      C    G     D       Em      D      Em
They make it bearable enough to help us on our way.
     Em                           C             
But still it feels nice to feel alive.
    G                              D
To try to find a house or home or someplace to thrive.
Em       C        G    D      Em                 C             Em      
It feels great to be alive except for all those times we feel dead.

    Em                           C
And how do we maintain our buoyancy in this
G                                 D   
Salty lake of shit and tears and murder and disease?
    Em     C      G         D       Em       C   Em
How do we keep ourselves afloat in all this sad stuff?

      C                          Em
I've gotta know the answers I've gotta know it now.
      C                          D
And I need to know the answers I have to know how.
Em         C    G       D      Em             D   Em     
We'll all die alone someday, I hope we don't die alone.
