solastasia
noun
The unsettling realization that your enthusiasm for life is waning, along with thinning ties to those you love, yet you struggle to change course because you're held back by an instinctive drive to protect yourself from non-existent threats.
From Latin 'solus' (alone) + Greek 'stasis' (a standing still), suggesting a state of loneliness that paralyzes progress. Pronounced "soh-lah-STAY-see-uh"
