Im just wondering if anyone knows who they truily are?

I was thinking about it today, i have no idea who i am.
When im with people i dont like but im trying to impress i call it the "fake joe"

..But i dont even know who the real one is, i have so many intertwining personalitys.
I act differnet with certain people 1 on 1.
I act different with groups, and differenet depending on the group.

My internal thought proccess also changes, i completily adapt and become somone else.

Im a chameleon.

Simple question, who here KNOWS who they are?
Is anyone real?
Im sure as hell not.
