Hanging Fire Analyzation

I thought that Hanging Fire was a very interesting poem. It was mainly about a girl (the speaker) and her depression. There are three stanzas, and in each one talks about what would happen if she died, and she repeats in every one that "momma's in the bedroom with the door closed." The rest of the poem is very random. The main theme is that the speaker complains about her appearance, her life, and a boy that I think is her brother based on how much she knows about him. For example he "still sucks his thumb in secret." 

I think that the randomness of this poem helps to make the repeating phrase, "and momma's in the bedroom with the door closed" stand out much more, and show the importance of it. In all her ranting the really serious things I got from the speaker were that her mother does not really care about her, and if the speaker were to die, no one would notice until it was too late.
