To manage stress, anxiety, and depression, try incorporating relaxation techniques like deep breathing, meditation, or yoga. Regular exercise can also improve mood and reduce tension. Prioritize sleep, maintain a healthy diet, and stay hydrated. Practice mindfulness to stay in the present moment and avoid overthinking. Talking to someone you trust or seeking professional help can provide support. Break tasks into smaller, manageable steps, and set realistic goals. Also, try engaging in hobbies or activities that make you feel good to distract from negative thoughts.
