Pieces.

Have you ever started to cry, and didn't really know why?
Feeling like, your heart was moving faster than your mind?
Like, what you feel is so surreal .. & your thoughts just can't deal?
I can't tell if I'm sad or if it's something more.
When confusion gets the best of me, I can't seem to find the rest of me.
There are pieces of me that I am not sure whether or not need to rediscovered or uncovered.
Who am I?
