How do you explain something you can't quantify?

I know my life is different than others. I'm at a loss as to by how much, in what way or to what degree.
I live clueless but it's not by choice.

It's very difficult for me to identify what I feel, put words to what I experience and compare my existence to anyone else's.

I'm staring at a mirror while standing behind the wall.

I can barely see me let alone you.
