I like the Yesterday, Today and Tomorrow stanzas. They were my favorite and they fit together quite well. :) Just my only critique with the poem, is some of the rhymes you did felt forced to me, like it didn't flow as well as it could have. :S Could be that or I just don't like rhyming poems much.
But I like the emotion you conveyed in this poem. I can relate to this and it sucks. -hugs- stay strong, things will work themselves out. :)

Amazing work:)
Great",
