Sad "Metaphors" of Sylvia Plath

In the poem”Metaphors” Sylvia Plath is portraying her pregnancy in metaphors. Her nine syllables riddle is actually this nine line, nine syllables poem about herself during pregnancy. Pregnancy is a strange time when one’s body does not seem to belong to them; another person is being constructed within it. One can imagine the lack of control one must feel in this period. Especially a sensitive woman like Sylvia Plath this time of her life probably seems like a nightmarish dream.
Sylvia brings in the images that metaphorically describe her state of being and the way she feels about her newly acquired “passenger”. Especially in the line ” A melon strolling on two tendrils” we get a sense of how she might look physically – a very late term pregnancy, that she looks as if a melon stood up on its tiny vines and tried to walk.
Ambivalence is felt lightly in Plath’s voice, it seems as she is unsure of how to react to her current state. She seems to have no feelings of happiness or sadness, unlike many mothers-to-be who are overjoyed by their pregnancies.
This is a wonderful yet dreary poem, Plath seems to convey to us the ambivalence she experiences towards her state and in a way questions her purpose in life. Not only that, it seems she would reverse her state if she could “Boarded the train there's no getting off” , but it’s too late now.
Knowing Plath’s biography, it is probable that she had some psychological issues during and after her pregnancy.(she was suicidal and eventually succeeded). It is possible that her last and successful suicide attempt was due to an untreated postpartum depression.
