Why People Blame Themselves

This isn’t just false modesty or fishing for reassurance; some people do believe that they cause every bad thing all or most of the time.

Blaming yourself when something goes wrong might, relates to a general tendency to make internal attributions for failure in which you see yourself as inept, foolish, or irresponsible. That tendency might motivate you to attribute your successes to external factors, such as fate, chance or luck, as well.
