Before starting a conversation with someone you are concerned about, be sure to have suicide crisis resources on hand. Ask directly, “Are you thinking of ending your life?” Don't ask in a way that indicates you want "No" for an answer like “You are not thinking of suicide are you?”
“I hear how difficult things are for you. But have you always wanted to die? Maybe there is a chance you won’t feel this way forever. I can help.“
Help the person access resources.
