A different pace does not mean you have forgotten how to care.

Caring is easy to confuse with output. When you were faster, the evidence was everywhere: the meals made, the calls returned the same day, the plans you carried for everyone. If your pace changes through age, illness or plain exhaustion, the evidence thins out and it can feel as though the feeling itself has gone. It has not; the measure was never the speed.

Let some of it be done differently: shorter visits, a message instead of a journey, help accepted so that something is left for the part that matters. Tell people what you can manage now. Most of them want your company, not your capacity.
