"Someone That I'm not"

I hide myself from the outside world
You think I'm someone that I'm not
As your perfect life goes by
I fall deeper in this whole
This hell-hole that you call my life
But you don't see the pain I'm in
Because I hide behind a smile
It's all because of an innocent laugh
That you think I'm someone that I'm not
I have to be strong for the safety of my sanity
Or at least what little of it is left
For if you knew the real me, the person that I am
And not who I pretend to be
You'd lock me up forever more, and throw away the key
Afraid I'd hurt myself or others
So if I quite pretending tomorrow
You'd say I'm someone that I'm not
But in reality, this life I live is all a lie
You think I'm someone that I'm not.
