It's been quite some time since I've had what I think of as a bona fide panic attack, but I think I had one last night. My mother died a few weeks ago, and I've been in and out of anxiety and depression ever since, with the anxiety usually manifesting as health anxiety.
I was doing okay yesterday, was working on various projects, had pizza for dinner, and about half an hour later started feeling shaky. Cold sweat, nausea, trembling, racing pulse, churning stomach. No real chest pain per se, but naturally my mind went to "heart attack." I left the house and walked around the block, thinking that this would burn up some of the adrenaline. I managed the walk fine, with no pain, but came back inside and promptly threw up my pizza. My pulse continued to race and only subsided after I took a Xanax. The pulse has been fine today, though I feel exhausted and still shaken from the episode.
Does this sound like a panic attack, or something worse? Naturally, the health anxiety keeps telling me this was a heart attack. For the record, in the last nine months, I've had three EKGs and a stress test, all of which were fine. My cholesterol is good, and my blood pressure has been well under control for over three years. I'm about twenty pounds overweight, but don't smoke or drink.
