The Virtual Therapist is an innovative mental health application designed to provide empathetic support and mental health guidance through AI-powered conversations. The project leverages the ChatGPT API to offer real-time, meaningful interactions, catering to users who are dealing with stress, anxiety, or other mental health challenges. By creating a safe, conversational space, this app aims to promote mental well-being and help users track their mood patterns over time.

Key Features:

Real-time Chat Interface:
The app offers a friendly chat interface where users can communicate with a virtual therapist.
The ChatGPT API is used to generate responses that are empathetic, non-judgmental, and contextually aware, providing a sense of understanding and support.

Mood Tracking and Visualization:
Users can log their mood daily or as often as they wish, using predefined mood categories such as "Happy", "Sad", "Anxious", "Calm", and more.
The app stores these mood entries and visualizes them over time using graphs and charts, allowing users to see trends and patterns in their mental health.

Personalized Mental Health Tips:
The application provides personalized mental health tips based on the user's mood entries.
These tips could range from relaxation techniques, breathing exercises, or motivational messages aimed at improving the user's emotional state.
Secure and Private:

The app ensures that all user data is securely stored and not shared with any third parties. Sensitive information such as mood entries and conversation history is protected.

Technical Overview:

Frontend: The front end is built using React, which provides a dynamic and interactive user interface. Key components include:

Chat Interface: Enables real-time text communication with the virtual therapist.
Mood Entry Form: Allows users to log their mood along with any notes they want to add.
Graph and Visualization: Displays a graphical representation of the user’s mood entries over time, using libraries like Chart.js or Recharts.

2.Backend:
The backend is developed using Node.js and Express, acting as a bridge between the frontend and the database, as well as handling API requests to the ChatGPT model.

API Routes:

chat: Manages conversations with the virtual therapist using the ChatGPT API.
mood: Handles storing and retrieving mood entries.
tips: Provides mental health tips based on user inputs.
Database:

SQLite is used to store user data, including mood entries and chat history.
Models are defined to manage user information, mood entries, and user settings.

Integration with ChatGPT API: The app uses OpenAI’s ChatGPT API to generate responses. During each conversation:

The frontend sends the user’s message to the backend.
The backend formats the request and sends it to the ChatGPT API.
ChatGPT returns a response that is displayed in the chat interface.
This approach ensures that the conversation remains relevant and contextually appropriate, providing a near-human conversational experience.

Mood Tracking Implementation: Users can log their mood by selecting from predefined options or adding custom tags. These entries are timestamped and stored in the database. Over time, the stored entries are used to generate visual insights, helping users monitor their emotional well-being.

Mood Categories: Happy, Sad, Anxious, Neutral, Angry, Stressed, Calm.
Mood Visualization: Charts are generated to show daily, weekly, or monthly trends, using libraries like Chart.js.

Deployment: The project can be deployed using services like Render, Vercel, or Heroku.

The front end (React app) is deployed separately to a static hosting provider like Vercel or Netlify.
The backend (Node.js server) is deployed to a service like Render or Heroku, ensuring the server is always accessible.
Environment variables (such as the ChatGPT API key) are stored securely using .env files, which are excluded from the repository using .gitignore.

Implementation Steps:

Set Up Frontend:
Initialize a React app with components for the chat interface, mood entry form, and mood visualization.
Design the UI using CSS and component libraries like Material-UI or Bootstrap.
Implement API calls to the backend for fetching chat responses and mood data.
Build Backend:
Create an Express server to handle API requests.
Define routes for chat, mood entries, and mental health tips.
Integrate SQLite for database management.
Integrate ChatGPT API:

Set up a route to handle user messages and generate responses using the ChatGPT API.
Ensure each conversation is contextual by maintaining a conversation history.
Implement Mood Tracking:

Create a route to handle mood entries and store them in the database.
Develop frontend components for users to add and view their mood entries.
Add Visualization:

Use libraries like Chart.js to create graphs that visualize mood data.
Display mood trends over time, enabling users to monitor their emotional state.
Deployment:

Deploy the frontend and backend services.
Secure environment variables using .env files and ensure sensitive data is not included in the repository.
Test the app in the deployed environment to ensure everything works seamlessly.

Potential Future Enhancements:

Emotion Detection from Text: Use NLP techniques to analyze user messages and automatically detect emotional states.
Voice Interaction: Implement voice-based communication for a more immersive experience.
User Authentication: Add user accounts to enable multiple users to use the app with personalized settings.
