Is it really me?

The one you spoke of last night
was that truly me by your side?
taking care of the ill you
putting a smile upon your face
you started to believe in such fairy tale stories
is it really me that is talking to you each night?
when nobody is awake at night
spending every moment until day light
is it really me that is holding you each time?
whenever your shaking from the cold
the warmness from the hug from the inside
I'm sorry that it has to be this way
i told you many lies
but never once i told you the secret i hide
I'm not who you think i might be
when I'm not in control of my very own mind
who is this guy?
in reality it's just me
who is really this guy?
I'm sick on the inside
is it really me?
when i have another personality
which my sickness consume me each time
is it really me in end?
that is a secret i must forever hide inside
