Dm   Gm                    C      F
I pretend like I'm alright, I run fevers through the night
Dm      Gm                    C
And she makes me sweat like hell
          F
'Cause I swear she's bad for my health
Dm      Gm                            C
Doctor, doctor, you've got to help me out
               F                    Dm
She's right behind you, hurry, turn around
            Gm                      C
Oh, my mistake, I guess I was just dreaming
   F
So back to the matter at hand
Dm         Gm                  C
But like I said, she's in my head
             F                      Dm
She's in my closet, she's under my bed
            Gm                  C
It's the lovesick crush from hell
        F                         Dm
And I swear she's bad for my health


[Chorus]
Dm          Gm                C
Bad for my health, bad for my health
       F                          Dm
And I swear she's bad for my health
            Gm                C
Bad for my health, bad for my health
       F                    Dm
And I swear she's bad for my, my
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh


[Verse 2]
Dm    Gm                      C            F               Dm
I see things crawling on my walls, I need more than Tylenol
        Gm          C            F                  Dm
And my ego flew so tall, flying high, but now it falls
                    Gm                              C
I swear the room is spinning, I'm beginning to get sick
                          F                          Dm
I told you I'm in trouble, and my double vision's thick
                  Gm                            C
Can you turn on a fan 'cause it's hotter than hell
       F                          Dm
And I swear she's bad for my health


[Chorus]
Dm          Gm                C
Bad for my health, bad for my health
       F                          Dm
And I swear she's bad for my health
            Gm                C
Bad for my health, bad for my health
       F                    Dm
And I swear she's bad for my, my
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh

[Chorus]
Dm          Gm                C
Bad for my health, bad for my health
       F                          Dm
And I swear she's bad for my health
            Gm                C
Bad for my health, bad for my health
       F                    Dm
And I swear she's bad for my, my
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh
      Gm             C
Na na na na na na, ayo
      F                Dm
Na na na na na na, ayo oh oh oh
