Feeling overwhelmed and burdened by the stresses of life is a common experience for many. Instead of using the phrase "have the cares of the world on shoulders," there are several alternative ways to express this feeling. One option is to use the phrase "weighted down," which implies both emotional and physical fatigue. Additionally, "shouldering responsibilities" can convey a sense of being overwhelmed by the demands of life. Another option is to use the phrase "weighed by worries," which describes the mental burden of stress and anxiety. Alternatively, using the word "burdened" alludes to a sense of heaviness and responsibility.
