ChandraShekar00001/Hospital-management-System-Using-MERN ? reverse-engineered prompt

Build me a full hospital management system where patients, doctors, and admins can all sign up, log in, and see their own dashboard.

I want patients to book appointments, see their doctor, view prescriptions and medical records, message the clinic, and download discharge and prescription PDFs. Doctors should be able to approve or reject appointments, update patient records, write prescriptions, and chat with patients in real time. Admins should be able to manage users, doctors, patients, appointments, discharge details, and invoices from one place.

Please make it a complete full stack app with a clean React frontend and a Node and Express backend connected to MongoDB. Add secure login with roles, protected pages, file upload support if needed, notifications, and real time messaging. Include sample data or a seed script so I can test it right away. If you need to check current docs or best practices for anything, feel free to look them up online.
