Why do sudden and child losses undo me when other grief doesn't?

You sit with grieving families for a living. Most days you do it well — you know what to say, when to stay quiet, how to leave room for someone else's pain without drowning in it. Then a child dies, or someone is here in the morning and gone by noon, and something in you breaks that doesn't break the rest of the time. That is not a flaw in your training. It means you still believe, somewhere, that death should come in order — old before young, warning before shock. Every case that breaks that rule hits a part of you that hasn't yet accepted how the world actually works. The skill you use every day is real. It just sits on top of an expectation you have never examined. If these moments leave you unable to sleep, work, or function for days after, that is more than a belief to correct. Find a supervisor, a therapist, or a peer group built for people who carry this weight, and let them carry some of it with you.
