Anxiety!Tale Sans, or just Sans, is a short skeleton with a fluffy sweater he uses to cover up his face when he scared or anxious. Which is all the time. Sans has extreme anxiety and is afraid of everything and everyone, except for his loving brother Papyrus. Sans’ anxiety can cause him to freeze up or over-worry and overthink any situation. He’s always stammering and shaking, unless his brother comforts him. He… wasn’t always like this. Something changed him into an anxious mess, sometime ago.
