Recognize what makes this moment difficult
Acknowledge the event directly without turning it into a lesson, comparison, prediction, or silver lining. For a message about how to tell family you have caregiver burnout, use this factual base: record the care task, health instruction, schedule, cost, decision authority, and current risk.
Offer support that can be accepted
Offer one specific form of practical or emotional support and make clear that no immediate reply is needed. Assign one decision or task at a time and confirm who will do it, by when, and with what information. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Follow their pace rather than yours
Do not remove the cared-for person's voice, shame a relative, or promise care you cannot sustain. Use clinicians, safeguarding, emergency services, or legal advice for neglect, abuse, incapacity, or immediate danger. The recipient decides whether they want conversation, ordinary company, practical help, professional support, or quiet.
