Since this was a past job, it can be referring to what this job represents or means to you. This girl you helped she can be representing a part of you. Water represents taking in spirituality. It can relate to your relationship or beliefs of God. Paper cup is showing something disposable, or worldly. Changing the cup and bowl is showing how you are changing your ways of taking in this information or concepts spiritually. The dream is showing how you are trying to "mend" or help this spiritual part of you. Food represents taking in spiritual nourishment. Perhaps you are trying to nourish this part of your life that you feel you have put aside or is in the past. This relationship is not yet strong enough as she is weak laying on the floor. But with her getting up and pooping on you can symbolize cleansing that has or is needing to take place.
