Remember Alani Morrisette? If she is not a catter she should be.
She claims she is a Highly Sensitive Person (HSP) and that she is part of the 20% of the population that is the polar opposite of the 20% narcicist population. HSP's have too much empathy, creativity, self consciousness and feel they don't belong. They feel different than other folks. I think she has a point and science agrees. Brain scans reveal some real differences in the amygdala and reasoning centers.

Move over Carl Jung there is a new personality type in town.
The highly sensitive person is normal but feels things more deeply and think about things more deeply. This is not a disorder but is confused with autism, Aspergers and anxiety. There are advantages to this personality but has drawbacks as well.

I hope this rings a bell.
