Lead heart

Lead heart
They say I have a big heart
That's true but here's the sad part
The only part
It's made of lead
At times it's so heavy
And my mind grows so weary
I feel dead
My head
Caught in a toxic cloud
Of lies, bittersweet memories and broken dreams
My thoughts fill my skull
Till it seems
Like it's bursting at the seams
Full
Beyond its limits
Each day my heart grows bigger
And so each day, heavier
With the weight of a billion bullets
And only one to end it all
But still I walk on
The beating
Is still going
I carry on
With my heart of lead.
