I can meet every plan and still teach everyone — why am I overwhelmed?

You accommodate now. You say yes to every plan, every change, every request. And you teach — you explain things to people who could learn them on their own. This looks generous. It feels responsible. But it is also how you built the overwhelm you are in. Here is what flatters you: the idea that you are simply more capable, more patient, more needed than others. Strip that away. Being the one everyone depends on is not proof of your value. It is proof you never said no. What is in your power is not other people's plans. It is your own answer to them. You cannot control how many people ask. You can control what you agree to carry. And if this has gone past habit into real exhaustion, say so to someone — a friend, a manager, a doctor. That is not failure either.
