Solitary Confinement

My walls, they are thick
My mask is in place,
A smiling and confident
Happy-type face.

My windows are shuttered,
Nothing can get in
Pay no attention
To behind my grin.

Inside I am scared,
Insecure, uncertain.
A seethe of anxiety,
Behind the curtain.

Someone assured is
A manner I'll affect
My vulnerable self
I must protect.

No one can know
How in myself I doubt,
I'll keep myself in,
And I'll keep you out.

Fortified defenses
Is all I have known,
But they keep me safe.
Safe...and alone.
