Who am I?

It's late.... or perhaps that would be early. I'm not sure anymore. I'm not tired right now so I've been thinking. Just who and what am I? Do my friends really know me? Do I really know me? There's so many sides to the person that I am, and the person that I was, that I find myself unsure of the real me. Thinking back on things that I've done or said, some I'm proud of. Others make me ill. Some seem surreal, like I wasn't the one who did it. And thinking about things that I may or may not do. Which facet of myself will affect my choices? My mind wanders about with what has happened, what is happening and what has yet to happen. And again I find myself asking....

Who am I?
