There is an underlying pattern behind every emotional state: a triad of “BAT”
Emotions are physically embodied – they exist in your nervous system and are distributed through the entire mind-body system. Posture, motion, facial expression, heart rate, tension, temperature, breathing, etc.
Emotions are associated with attention – your focus goes to different things (eg problems v. solutions or worries v. achievements). Your vision of mental images may change too (near/far, fast/slow, etc.)
Thoughts and language change too — there are certain patterns of language (eg. have to v. want to or can’t v. could). Then you may create significance or meaning through thought (eg. this means I’m a failure or I’m worthless). Often there can even be entire stories associated with this (I can’t do it because I’m a woman).
