If you can recognize that you will never be without yourself, then you will never have to fear being alone again. If you can accept that you may be the only one in your whole life who won’t ever leave you, then you can relinquish the fear of being left by another.
Though you cannot control another’s choice to leave or the sudden death of someone you love, you can find comfort in knowing that you’ll never be abandoned by yourself. Once you come to appreciate your own company and value your own self, you’ll forever free everyone else from having to accompany you. And, paradoxically, this is usually what attracts everlasting companionship to you.
