liminascent
adjective
It's the sensation of awakening to a day where the idea of engaging with existence is nearly unbearable; you don't wish for death, nor to fade away, but instead, you long to pause, to suspend your being altogether, resting in a familiar void.
From Latin 'limen' (threshold) + 'nascere' (to be born), indicating the threshold state of being unmotivated to cross into daily existence. Pronounced "lih-MIN-uh-sent"
