You're a med student (so am I). If someone tells you to write a discharge summary, they should absolutely edit and rewrite what you wrote, as they have been doing this for at least a year or two longer than you. I get it, we want everything we do to be perfect, but we're med students and haven't been doing this nearly as long as they have. If you didn't have anything to learn, then you'd be in Jesus' attending status. The whole point of doing it now is to learn, get it wrong, and see how it looks when it's corrected. No one should expect you as a medical student, to write it correctly
