Understanding warning signs of suicide means looking for expressions of wanting to die or to harm oneself, or changes in behavior that suggest planning, hopelessness, or a shift toward self-harm. Giving away belongings is a well-known sign because it can indicate someone is preparing for an end of life or a major life change. Relationship problems reflect acute distress and can accompany escalating risk, especially when paired with withdrawal, mood swings, or hopeless thoughts. Talking about harming others can signal violent ideation, which is a safety concern and requires attentive response, though it’s a different focus than self-harm. Buying a new car does not inherently signal suicidality or intent, and is generally just a normal life decision. So the item that is not a warning sign is buying a new car.
