I will break

I am an egg
And my shell is not invincible
If you don't stop hitting me
You will break me open

I am fragile like glass
And my smoothness is not strength
If you bang me too hard
I will definitely break

My head is a bulb
And I have bright ideas
But if you drop me
You will surely break me

My heart is a pressure pump
Pumping the stuff of life
But if you play with it
It will break to pieces

I feel like a bowstring
pulled to a taut
If you don't release me
I know I will break

And you are to blame
