Who am I?

I don't know. It's just like if--I don't know, it's like--I don't know. I can't even begin to explain it because I don't even know if I know what it is. So I can't really explain it. Because I don't know. I don't even know, like in my brain or in my heart, what I am really feeling. I mean, I don't know if it's pain or sadness or anger--I don't know.
