Verses:
Gm                                   
My heart doesn't pull me the same   
Em
Oh all my carelessness is gone
Gm
And ya know my mind doesn't owe me the same
Em
But girl my struggle goes on and on
Gm
My soul wants to pull me away
Em
But all this hopelessness has won
Gm
And all these dreams wanna take me away
Em
But this feeling just makes me stay

Gm
Apathy, has it's hold on me

D---G              G/A
Lonely, I feel so lonely
Em                           G/A
Girl hold me, won't you just hold me
D---G             G/A
Lonely, I feel so lonely
Em                           G/A
Girl hold me, won't you just hold me


Bridge: I hold a B power chord the whole time and play with harmonics.
