Don't worry yet! I know I walked out of my oral psych saying "WTF, I think I failed!" It was a long two weeks! It just shows that you are a typical canidate.
If you walked out with no worries and no stress from the doctor I would say you probably omitted a lot of info you probably should have mentioned or you lived such a boring and squeaky clean life that you have little to life experience.
Sounds like your going through what most of us did!
