Misunderstandings and truths

Where has my smile?
The real smile?
For this it is in my face is false.
It hides my sorrow and anger.
Hide the pain I carry with me.
Maybe I can fool others,
But do not mistake myself.

Inside me the pain speaks louder
I do not know how long it will take.
It's a lot of pressure,
And sooner or later
The mind just giving in,
What would it take,
And lets shoot.
I'm certainly not the same.

I'm not as vulnerable, but I'm not iron.
Even the most powerful man
An hour will fall!
