I’ve always said I’m not afraid of dying alone. It’s because I always imagine dying is the thing at the end. A future event. But we’re all dying all the time. And being alone at the time of my death isn’t the thing to fear it’s being alone up to that time. It’s being alone now. That’s what dying alone is. And this realization makes me afraid.
I think this is a good thing, you came to an important realisation and your fear is doing its job of warning you about a very real danger. As long as you listen to it and don’t let it overwhelm you maybe it can help you take action.
