Halez's "abandonded" is a raw, direct address to a father who has left. The speaker feels betrayed and alone, and she describes herself sitting in the dark with "horrid thoughts." Light and dark run through the whole poem: her father was the light, and without him she is lost in a "dark sea." A small joke, "I shouldve bought a lamp," sounds like she is trying to cover pain with humor.
The poem shifts as it goes on. Early lines sound angry and bitter, but later the speaker turns childlike, calling him "daddy" and "superman" and talking about "meanies" hurting "your little girl." The ledge she clings to is the image that matters most. It has been cracking for eight years, and now that she is seventeen her arms are sore and she admits she "kind of want[s] the relief." That line is the most worrying one, suggesting exhaustion and thoughts of giving up. The ending turns bitterly sarcastic, imagining him too late, even for her memorial. The mood is lonely, tired, and aching.
