Which among the following is an example of a recent stressor that could elevate suicide risk?

The correct choice reflects a significant and often overwhelming life change that can impact an individual's emotional and psychological well-being. A loss of income is particularly distressing because it directly affects a person's financial stability and can lead to feelings of hopelessness, inadequacy, and increased anxiety about the future. Such stressors are critical to consider in the context of suicide risk, as they may contribute to feelings of despair and a perceived lack of options for coping, thus heightening the risk of suicidal thoughts or actions.

In contrast, receiving a promotion, socializing with friends, or completing a project are generally seen as positive experiences that can enhance one's mood and increase feelings of accomplishment and connection. While any life event can potentially act as a stressor depending on the individual's circumstances, the nature and context of losing income present unique and acute challenges that can exacerbate underlying mental health issues, making it a notable risk factor in suicide assessment.
