Porosity

Just one more obvious spot that I can see -- the punctuation in the first stanza needs addressing, eg:

The glass was full.
Tender emotions,
carefully contained
within the boundaries
of a plastic cylinder. 

The only comparisons I can think to make here are with Plath's writing -- and where she was all woe is me and gosh it's hard, your words are strong and empowering.  Been downtrodden, got new boots, making your own footprints.
