Look at me

I am the one you always look at
But the one you never see
The one you always talk to
But you never listen to me

You turn to me when all else fails
But you're never there for me
I push it all aside in my mind
But deep down it really does break me

There's nothing that I can say or do
To change just who you are
But for all that I want to be
I will never be in your heart
