Your boundaries should protect your kindness from becoming self-neglect.

Kindness without limits stops being kindness and becomes a slow erasure of yourself, though it looks generous from the outside the entire time. Boundaries are what keep giving sustainable, since a person who is depleted has nothing left to give and often becomes resentful about it.

Check whether your generosity is currently leaving you with anything. If it is not, reduce it somewhere specific this week. Sustainable kindness helps more people over time than the depleting version does.
