So in panic attack.. If u experience unexpected attack of... Palptation(i.e being aware of ones own heart beat), sweating, shortness of breath, chest pain, nausea, dizziness,fear of losing control (as in screaming like crazy person) if u have 4 sx which last 10 min which occur recurrent On the other hand in GAD -its just excessive worry and anxiety it associated with restless, easly fatigue, difficulty concentrating, sleep disturbance etc... In if those things Impairs u from ur daily routine u have anxiety!!
