You keep going because the alternative is a betrayal of your own conscience.
The community you lost was built on a conditional connection—one that required you to ignore reality for the sake of comfort. The community you have now, even if it's scattered across the internet, is built on the radical foundation of care.
You move forward for the person you still are: the one who values evidence, who protects the vulnerable, who didn't abandon their ethics when it became inconvenient.
It's exhausting. But you are not keeping a vigil for the past. You are holding a line for a future worth having. The "how" is one breath, one N95, one small act of self-respect at a time.
