Who are you?

Who are you,
to judge me now.
Who are you,
to tell me that I'm fat as a cow.
Who are you,
to stand up in the crowd.
Who are you,
to tell me I shouldn't be proud
Who are you,
to tell me I should quit.
Who are you,
to tell me that I don't give a shit.
Who are you,
to tell me I will fail.
Who are you,
to sentence me to hell.

Who am I?
I am only me.
