Shining through darkness

They say that in a world shrouded in darkness, even if you’re just one heart living in it, you must shine as bright as you can and extend your hand to help others. That’s what I try to do, but it hurts to carry this burden. Everything is dark now, and there’s no way out, but I keep piling it on until I’m completely overwhelmed. There’s no further explanation for my frustration—I'm trapped in an endless fear of existence. I can’t believe this is my life; it haunts me. Curse it! They bless me, but I’m so sick of being trapped, all alone. This family isn’t enough. Am I ungrateful for wanting something more, something warmer? Am I overthinking? I hurt those around me, and it terrifies me. I’m so tired of breathing this suffocating air.
