Prison

Cell walls built by society,
With rules to adhere.
If you breach the acceptable,
You had better beware.

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?

You can't.
