What is the theme in the poem depression?

Many poets—countless poets—have written about depression from the perspective of dealing with it either as a malevolent force that brutally assaults the creative process or as benign guardian angel helping the writer to dig into places one usually fears to tread. Sanchez appears to be doing something different and a little more rebellious. Oddly grotesque imagery, fragmented punctuation and contradictions within individual thoughts, the much longer first stanza seems like an interior monologue not by a person suffering depression, but the depression itself as a living, breathing, sentient entity. The second stanza subtly shifts in tone and structure so that it now seems as if the person that the depression has assaulted is now crying out for in pain for help.
