Has anyone ever experienced a panic attack coming on right after exercise or physical exertion? The other day, I had been doing some physical work and became very breathless. I sat down to catch my breath and then got scared about it and a full blown panic attack hit me. I felt like I couldn't get a deep breath. I guess I was bordering on hyperventilating. Anyway, it was bad enough that I had to leave work - the first time that has ever happened

. I even went to the doctor to see if my heart was ok. The doctor said I was OK. Today, I was scared to return to work, but I made it. How miserable!
