And... I agree. Not that she's a fraud, but that it's how I think most of us feel at that point. Actually, it's how ALL of us feel. It's just that some won't admit it. I will.
Attention medical students and residents: THIS IS NORMAL. You just don't realize it until you're actually going through it.
As a 3rd year medical student this terrified me. I was seeing REAL (OMG! REAL!) PATIENTS and had no idea what I was doing. The attendings would point out the substantial gaps in my knowledge and I'd feel like there was absolutely no way in hell I'd ever know that much.
Toward the end of my 3rd year was a rotation with Dr. Griffith, an absolutely brilliant internist. He was a nice guy, but always made me feel like I knew little, simply because he had all the answers I didn't. Seated next to him at an end-of-year lunch, someone pointed out to him that he'd now been an attending for 6 years (yeah, in retrospect, he's not that much older than me). I quietly asked him "and do you still feel like you don't know anything?" He laughed and said "I don't know anything."
And, folks, it never goes away. I've now been an attending physician for over 15 years, much longer than Dr. Griffith was at that time. And I still feel like I don't know anything.
I think the issue is that inwardly we're still the same people who went to college, made it through medical school, survived residency... but we're still ourselves. Somehow we expect that, by being given the title of "Doctor" we're suddenly endowed with a sort of medical omniscience... and it doesn't happen. I don't feel any smarter today than I did when I stepped out of grade school, or high school, or college. Even though I KNOW that through learning and training I've amassed a decent amount of medical knowledge, it's not something that any of us is consciously aware of.
In my experience, the only way any of us realize how far we've come is when we compare ourselves to someone at a previous stage in our training. When I have the occasional medical student or resident spend a few days with me, I'm amazed at how much more I know about neurology than they do, even though I don't feel any different than I did at their stage. It's only in comparison to those behind us that we realize how far we've come.
And, if they ask me if I ever feel like I don't know anything, I tell them "always."
Good luck, Haley!
