Keep the message proportionate
Use the shortest explanation that still tells the truth about the event, impact, and current position. For a message about how to support someone living with depression, use this factual base: reflect what the person has told you, any immediate concern, and the practical context without diagnosing them.
Give timing that can be trusted
Give a realistic date, a simple option, or a direct yes-or-no question and avoid vague promises such as soon. Offer one manageable form of support and ask directly about safety when you have a serious reason to worry. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Close the loop without drama
Do not shame, threaten, promise secrecy about imminent danger, or make yourself the only source of help. If someone may harm themselves or another person, contact local emergency or crisis services and a trusted nearby person now. A calm ending is more credible than a warning, a grand gesture, or language designed to provoke a response.
