Imposter syndrome is characterized by those who are unable to own their own accomplishments and are in constant fear of being exposed as a fraud. Many people afflicted with Imposter Syndrome feel they are unworthy of whatever position they have attained and that or unworthy of their position.
A 1978 study found that the phenomenon was unequally common in high-achieving women. Therapeutic interventions were statistically successful in allowing such women to be aware of their achievements and to internalize their success.
The American Psychological Association has an excellent piece on the feelings of being fraudulent. Their recommendations for moving past it are:
Talking to mentors
Remembering what you do well
Realizing no one is perfect
Changing your Thinking
Talking to someone who can help
