which one is i?

there are voices in my head.
just as indecisive as I am,
sometimes taunting me,
at times soothing me,
tolerating my indolence.
it is like the seasons,
forever changing—
each voice louder than the next.
they sound like me
but do not think like me,
who's to say which is which?
i listen and listen,
for the voice that used to leave my lips
before they take over and i lose what is mine
