with my evil twin

I'm having a fight 
with my evil twin
and though I use all my might
I don't know if I'll win
'cause it's not all black
and it's not all white
and that's not something
either one of us likes

I'm always at war
with my evil twin
I tell you, friend,
where to begin
'cause I don't know 
I don't have a clue
what caused my mind
to split in two

          I've had therapy
          drugs were there for me
          I don't care, you see
          what I must do
          all I know as fact
          this sad balancing act
          always alert for attack
          it can't be true

I'm exhausted from this fight
with my evil twin
but it seems as addictive
as love or heroin
but here we keep moving
and here we stand still
each with our pride
and our own free will
