Maybe someone knows what exactly causes the heart to pound? Like now i just woke up and my heart was pounding lifting my belly and my chest up like always since the first panic attack it has become ''normal'' to me. But just after a few minutes of being awake it stopped beating so hard, my pulse didnt change, the only thing that did was that i didnt feel me heartbeat, and my belly and chest werent rising so much. And i know it wont last long, maybe 2hours , the its back to pound town.
