Or I trust not at all. 

My heart was made to break, 

Fragile as glass 

As clear as crystal 

Or hard as stone

impenetrable as marble. 

A fight either way

Leaving scars and scratches 

One day

The next, an impenetrable barrier

We both pound upon 

I, afraid, hurting, numb. 

Fear is my limit, my wall, my cage.
