Superglue

The glue that held together all the pieces
I shattered into when you dropped me from above
Always so careless, you were
The glue that made me feel whole again
Melts now in this heat
And I am left as nothing but a pile of broken pieces
No glue is strong enough to hold together
Until finally
My heart explodes
My lungs collapse
I breathe my final breath
And like broken bits of a glass dropped
Someone sweeps me into a dustpan
And throws me in the trash
