Out of Place

I always get the feeling that I don't belong wherever I am, whoever I am with. I'm really not sure why I get this feeling but it's always there.

Maybe I am.

Or maybe it's just a feeling.

My sister and her friend say that I am very outgoing, very friendly, very accommodating. My few high school friends say that I tend to stand out. My college friends think I'm shy. Am I schizophrenic?
