Have You Taken Me Too

I've caught you out a million times,
But you still have no truthful reply.
I've put my life on the line before,
But still you're living a lie.
No matter how far I strive to go,
You seem to always pull me down.
Even if you Ruled the World,
You'd still be clawing at my crown.
If I had everything you'd steal it,
And if burn it if I had nothing else.
You've taken all I own and cherish,
Sometimes I think do I even have myself?
