Dealing with profound loneliness ("solin sólito") requires both self-care and reaching out: 1. Acknowledge your feelings without judgment. 2. Engage in self-reflection to understand the root of your loneliness. 3. Develop a self-care routine including physical exercise and healthy habits. 4. Pursue hobbies or interests that bring you joy. 5. Reach out to friends or family, even if it feels difficult. 6. Consider joining clubs or groups aligned with your interests. 7. Practice mindfulness or meditation to stay present. 8. Volunteer or help others to create meaningful connections. 9. Seek professional help if loneliness persists or deepens. 10. Use technology to connect with others, but balance it with in-person interactions.
