Im 26M, I had to do an inventory for work for 3 months overnight and which started 2 months of the worst anxiety of my life , I get worked up and feel like o have trouble breathing which leads to me reading about heart failure symptoms and then I start believing yea I do have 90 percent of these. And then I schedule a doctor's appointment then feel fine when it comes to go so I cancel. How mentally cooked am I and also could it be heart failure, would I know?
