我就一颗心你看着伤吧

This username conveys a sense of resigned acceptance to one’s own emotional pain, almost saying, 'Here is my heart, do with it what you will.' It expresses vulnerability and perhaps some frustration or sadness. The owner might be referring to having given someone everything, only for that person to hurt them.
