No one can tell

Since I met you,
Ive always known,
That theres a weakness in you,
Not normally shown.
You try to hide it,
And pretend you're all right,
Battling yourself,
Putting up a good fight.
Continuing on,
With no way of knowing,
What you're leaving behind,
Or where you're going.
Though you feel,
You're hiding it well,
Its seeping through the cracks,
But no one can tell.
No one but me,
That I must say,
But you pushed me aside,
As if I were in the way.
So I'm leaving you,
With one last token,
Take it and leave,
My hearts already broken.
Your damage is done,
That much is true,
And yet you don't know,
What I knew about you.
Though you may think,
You're hiding it well,
Its seeping through the cracks,
And no one can tell.
