Fed up with Hunger Lyrics

Cover art for Fed up with Hunger lyrics by Saintseneca

This song talks about sleeping with someone and finding a point where you miss accomplishing goals and doing things for yourself "I miss behaving".

"How does one so young become so fed up with hunger?" This line to me seems like it has to do with being done with waiting for sharing intimate affection with someone.
