lost myself

I a world with so many people and so many things, I feel like I'm not really there it like I left it a long time ago but I can still see what I saw. some of the things I see I remember but most of the things I see feel like there's new. in this world where everyone seems to know who they are, the question is who am I? am i what everyone want me to be or who i want to be? and when will this all be over?
