Self-deprivation

Imprisoned in my own mind,
Slave of my own heart.
My own thoughts are a maze,
My own steps I can't trace,
I feel I'm someone else,
Someone strange.
My soul is in a different place,
Am I deranged?
I'm in a deep, dark, deadly cage,
Locked up by rage,
Keys are in my hand,
I can't get myself out.
I don't understand,
Is it that I don't want?
Or I'm not strong enough,
Truth is I planted myself here,
And this misery has overgrown.
