Camouflage

I have many identities. I use one at work, one at home, one with my friends and one when I visit my parents and siblings and I probably have quite a few more. But how do I know which one is the real me? Is it just one? Maybe it is all of them at once or am I just as faceless without them as the characters I draw? I don't know... it sometimes feels like I am pretending to be someone else even when there is no one else around.
