According to Osho, feeling more alone after a loss exposes your unhealthy dependence on others as your reason to live. Aloneness is not a problem but the only doorway to truth and psychological health. Use the shock to turn inward, live for yourself, and create from your own joy—friendship, love, and creativity arising as expressions of your fullness, not substitutes for it.
Losing someone shows you were leaning on them; learn to stand on your own and let love and friends come from your own happiness.
