I personally liked the desperation of trying to gain back something dear that was lost (which I can relate to).
I'm content with knowing what is told within this poem here. Suggestion/Tip: furthering the "i can't" stanzas might make readers feel/connect more with the poem. or leave it the way it is because it's still good.
My only bit of "criticism" (maybe?) is that you mention love twice. I personally like keeping subjects within one stanza, so I would either merge the two love stanzas together, or cut the second one (only because I like the first one better).
