So at 32 years old I had my first panic attack this morning and it was a doozy. Initially thought it was a panic attack, but after about 30 minutes of strong waves of feeling like something is extremely wrong I decided to call an ambulance. Went to the ER and all my tests came back normal. After about 2 hours I felt good (albeit extremely embarrassed) so they sent me home. They attributed it to heartburn because I was recently put on a PPI for reflux. No mention of the possibility of a panic attack. 

After being home for about an hour I got a very short lived (talking seconds here) familiar feeling of panic, but I jumped into a game with a friend to distract myself and once I felt well enough, I went to sleep.

My question is, how do you guys deal with that constant fear of another possible attack being around the corner? It was one of the worst experiences of my life and it's now a constant, somewhat silent fear in the far back of my head. It's been less than 24 hours so I'm sure that's part of it, but I'm on edge as if I'm constantly right on the verge of it happening again.
