I Wonder If I'm Ever Missed By Anyone

I wonder....I really wonder. Am I ever missed by anyone? Do I hold any meaning or significance in anyone's life? Who am I to you?
These questions follow me everyday. I wonder if I am ever wanted or needed by anyone. If someone smiles at the thought of something I have done or said. If someone even thinks of me for but a moment. If someone would really take a second or even a minute of their life to think of me. Who really would miss me? - a question I find myself continuously asking, yet the answer I can never find.
We all want to feel like we mean something to someone, but do we really ever stop to think, who really cares about us as a person?
