Protecting your younger siblings from the stuff you went through is a quiet kind of brave.

Nobody claps for the older sibling who absorbs something quietly so a smaller person does not have to. It rarely looks like bravery from outside, because the entire point is that the younger one never sees the part you handled. That does not make it smaller. It makes it a kind of courage only you will ever hold the full record of.

If that is you, two things are worth saying. What you are doing counts, and you are allowed to tell an adult you trust that you are carrying it, because you were never supposed to do this alone.
