This poem's meaning is really up to you. You can even take it literally if you'd like.
I tried to express the feeling of two entities, both broken or fragile or vulnerable for some reason, helping each other through some period of time. The circumstance and nature of the relationship between the entities can change; the poem still applies.
I named it 'Symbiosis', because that is the most summarized form of what this poem was intended to describe. [In biology, a symbiotic relationship is when two organisms assist one another, such as a fish eating the parasites and such off another fish. One fish gets food and the other food gets cleaned.]

I tried to add some visual poetry, too, with each line looking a little longer than the previous line in a sort of stair-step pattern - as if you could climb up and be triumphant.

oh, and yeah this is iambic pentameter... heh
