Caged

I am trapped in a cage
that I built for myself
out of fear
out of failure
out of insecurity
Now I'm pleading for my freedom
Why won't someone let me free?
But I realize that my jailer
is the one and only me
How do I break myself out of this cage?
I've locked me up and thrown away the key
If only I had known 
now I'm stuck here all alone hoping that someone will set me free
One day I grew wings
broke free and flew away
but the trials of the world did force me to return
and I rebuilt the cage which I did spurn
with thicker bars and stronger shackles
and once again I plead for release but I've learned
that I live in a cruel cycle that cannot be turned
