Who am I?

I thought the day was fun,
But it\'s the opposite of that one.
You are the one beside me,
But it feels like I am nobody.
I want to escape these feels,
the feeling of loneliness
Coz it really hurts,
My eyes want to burst.
You were upset, and I listened.
I was lonely, yet you escaped away from me.
Am I somebody?
or just Nobody.
