Cognitive dissonance?

When people tell you you are great at something, but you don't know, or can't talk about it, and feel you can't live up to your parents/teachers expectations, that's a lot of stress.

Also if you thought you were great at something in school, but actually you find out you suck in the real world, if that was a major part of your identity, some people just can't live with that.
