Word Choice in The Secret Writings of Eros: Book 3- Fallout, Pain, Acceptance, and Perseverance

I am not as good at words as I would like to be sometime. But there are languages far more skilled at expressing things than English. Is there a word in existence that describes this feeling?
I have a feeling of desire for a feeling of desire. The sensation that there is no one I want, no one I pine for or lust after or seek with my heart.... but I do want that. The desire for something nameless, formless… an abstract idea. I know not what I want, but I know I want… something. This cannot be so unique a feeling. This is the inspiration for great writing (and poor writing) for generations. But is there a WORD for it?
