Was lying on the couch the other day and felt that my heart was going quicker than usual. Which I then started panicking. Checked my pulse and it was 96. I then had a full blown panic attack, finally settled down and went to sleep. But now I just feel my heart isn't beating properly, feels quicker than usual. But I check my pulse and it's around 75-82 everytime. I've had a cold for the last week and one of my ears are blocked. I feel kind of breatheless at times. Like I need to take a deep breathe. Surely if my pulse is between that range I shouldnt worry, and it's just my anxiety. Maybe I'm just so hyper aware of my heart now that I think its beating faster. When in fact it's not.
