Hi guys - I have always been an anxious person, sometimes medicated for depression. That being said, I never had anything that was physical in nature.   


About a month ago, I had a drinking binge, and the next day woke up with tightness in my chest, a racing heart, and difficulty breathing. This binge coincided with a downturn in my personal affairs - breakup, death, and financial issues.   


Over the course of the following weeks, I struggled with "attacks" of racing heart, dizziness, that escalated into me going to the hospital multiple times. Having been to the hospital many times and to various cardiologists, they all said nothing was wrong physically and acutely.   


Nonetheless, I am struggling with an almost persistent chest tightness, that after workouts escalates into a difficulty breathing and general sense of doom pretty much everyday, only culminating in an early bed time, and a lot of time spent clenching my chest in bed.   


There have been some times where I took a bunch of melatonin and beta blockers i was prescribed, and my heart was not racing, but I still felt the unease and sense of doom. 

Has anyone had similar occurrences and what the hell is going on?
