Why does surviving every crisis still leave me this tired?

You have kept the business alive through things that would have broken other people. That is real. But you paid for it with your own reserves. You did not notice the bill coming due. Survival mode feels like strength while you are in it. It is not strength to never rest — it is a debt. Every crisis you absorbed without recovering from it, you borrowed against tomorrow's capacity. The tiredness you feel now is that debt collector. You cannot think your way out of exhaustion. You have to change what you do with your hours, starting today. If the tiredness has turned into something heavier — a weight you can't quite name — talk it through with someone outside this work, not just alone in your own head.
