So, my heart started racing and pounding but went on for hours, then everything started scaring me. I was trying to go to bed and when I’d close my eyes I felt like I was being consumed into darkness and thought my vision was going out. The panic loop because of my strong heart beat was scaring the shit out of me and eventually I fell asleep. Does anyone else get a pounding heart that lasts for hours? Is there anything I can do?
