Full Empty

Have you ever noticed how difficult it is to completely empty something?
       Bits and pieces of debris always cling
            Dust and splinters, lint and hair
            remnants of broken dreams and shattered hopes
You can never really get rid of them

But I keep trying for a fresh start

Forget what I've tried to fill myself with
Vomit out the liquor, the poison
     Evacuate the darkness, the death
Expel the despair and fear

For how can I be filled if I am not empty?
