SciFi and Fantasy Art: No way out

----Prison----
Life is a prison,
Oh God let me out.
No one to listen,
To hear when you shout.
Climb the walls of insanity,
Ride the waves of despair.
If you fall it won't matter,
There's no one to care.
Used to wish for a window,
To see birds, trees and sky,
But you're better without one -
Stops you aiming too high.
Watching freedom is painful,
For those locked away.
Seeing joy, love and happiness,
Another price that you pay.
 
Hide the pain, carry on,
Routine is the key.
Don't let on that you're not,
What you're pretending to be.
Lock it all up inside you,
How badly that bodes.
Look out for that one day,
When it all just explodes.
Leaving naught but a shell,
Base functionality too.
But killing all else,
That was uniquely you.
So how do you grow,
With a time bomb inside?
Or how to defuse it,
Without destroying its ride?

My first attempt in corel paint. I'm learning, slowly but surely. any feed back is greatly appreciated.
