Mr Roget... Help!!

I need to know the word/expression/term that fits my disdain/dislike/disbelief in the human race, taken as a whole.

I know I'm neither sociopath nor psychopath ~ however many tendencies I share with both terms. I neither hate you all, nor want to kill you all, although... there are days...

I'm too optimistic to be truly cynical, I'm too hopeful to be called a pessimist. And yet...

... there are those days.
