Life transitions refer to major changes or shifts in an individual's life. This includes positive and negative events, and often involves significant adjustments to interpersonal relationships, work, education, and one's identity. Some common life transitions include graduating from school, starting a new job or career, getting married or entering into a long-term relationship, having a child, experiencing a divorce or the end of a significant relationship, relocating to a new city or country, and retiring from work. While some transitions may be anticipated, others may be unexpected and require adaptation. They can impact an individual's sense of self, relationships, and overall well-being.

Life stressors, on the other hand, are circumstances that cause an individual to experience high levels of stress. These stressors can be external, such as financial difficulties, work-related problems, family conflicts, or a major illness or injury. They can also be internal, such as self-imposed pressure to meet high expectations or experiencing a loss or disappointment.
