Mental Health Telehealth Web App

I need a full-stack web application that serves as a mental-healthcare hub where patients, therapists, and healthcare administrators can interact seamlessly. The core of the platform revolves around three critical features: • Appointment scheduling – patients should be able to book, cancel, and reschedule sessions in real time, while therapists manage their calendars and administrators oversee global availability. • Curated mental-health resources – articles, self-help exercises, and therapist-uploaded materials organised in an easy CMS-style dashboard, searchable and taggable by condition or topic. Stack as of now : Next.Js + React, Vercel deployment and Supabase backend. I have a vibe coded web app already made, this will be handed to you for testing, checking, verifying and making necessary changes as we discussed. The web app is almost build but due to non reliance on AI, I need someone to confirm operation and thereafter maintain it. Please note as mental healthcare data is very sensitive, compliance of storing and security of app and clients onboard is of paramount importance.
