Why can't I fool me?

Can no one see this smile in faking,
How inside nothing's whole,
And everything's breaking.
People say they know me,
That they can tell when I'm hurting,
But no one sees how this shell,
Is crumbling.

When they ask,
I tell them I'm fine.
They don't need to know how weak I am inside.
I've dealt with this most of my life,
Now I just take it in my stride.

They watch as I slowly fade away,
But none of them notice,
Because I always say that I'm okay.

My physical presents is there,
That's all that they need,
Because none of them need to know,
The pain that I feel,
where no one can see,
I can fool them all,
Why can't I fool me?
