This is not the kind of tired that sleep fixes. You have tried that. It is still there in the morning.
You have been performing okay for long enough that people stopped asking. Somewhere in there you stopped asking too.
You have been pouring from a vessel nobody has refilled. That is not a character failure. That is arithmetic.
You have been performing okay for so long that people forgot to ask if you actually are. Maybe you forgot too.
Your body went quiet because your mind would not. That is not weakness. That is your system protecting itself.
You are tired because you have been carrying this alone and pretending the weight is normal. It is not.
You have been strong in a way that nobody asked you to be and nobody noticed. That is its own kind of exhausting.
Rest is not giving up. It is what you do so that the version of you who finishes this actually exists.
You keep going because stopping feels like losing. But you are losing something right now too, just more slowly.
