All My Efforts

The batteries are low
and soon they will be empty
cause you need all my power
and I feel I got devoured
I will not give up myself
I will not let my life for you
these were all my efforts
I can give no more
I am nailed to the wall
in your treasury hall
all my efforts
now it's time we have to part
and walk our way alone
for so many years
you've been my companion
you will not reject me anymore
you will not be a nail in my coffin
you see I'm not the one
and to you I don't belong
these were all mine
I can't give no more
