Who is that girl?

I look at the mirror
who is that girl?
in her heart there's a horror
every time she makes a mistake
pieces of her disappear
her smile it's fake
herself she fear
her life it's shattered
it's ruined
her life, it's murdered
her day, it always darkened
she doesn't do anything about it
her life is taken
she doesn't want to admit
that her life it's broken
she tries, sometimes
in her dreams, nightmares
her feelings she bares
often everything for her it's a dare
no one cares
she's left alone
in this crazy world
who is that girl?
