I have a higher life events score too but think it's day-to-day stuff like being overweight and health issues that influence how well you can do things rather than a purely psychological thing like "depression" or "post traumatic stress", "anxiety", etc. All that stuff on the first page you fill out before you start answering the quiz; whether you smoke, etc. Just "normal" things that are continuous in your life but not particularly good for your mental health.
