And I'm exhausted,
Her hard lifestyle has her constantly weary. It’s not easy working them streets.
The particular use of words here also sheds light on the attitude she has toward her life. After the graphic desciption put forth in the previous line, most would describe a sense of displeasure or shame. However, Keisha’s use of the word “exhausted” here to describe her attitude toward sex with random strangers shows her comfortability with prostitution, and furthermore her moral detachment from the acts and lose of self worth. She views it as just a regular occupation.
