Jealousy is a complex emotion that encompasses feelings ranging from suspicion to rage to fear to humiliation. It strikes people of all ages, genders, and sexual orientations, and is most typically aroused when a person perceives a threat to a valued relationship from a third party. The threat may be real or imagined.

Trauma is an emotional response to a terrible event like an accident, rape, or natural disaster.

Immediately after the event, shock and denial are typical. Longer term reactions include unpredictable emotions, flashbacks, strained relationships, and even physical symptoms like headaches or nausea.
