I recently turned fifty and, until recently, can only remember twice that I had experienced panic attacks. 20 years ago when I split with my wife and last year when I almost fainted in a mall while battling a virus. So this year I have developed health anxiety. My ex-girlfriend had serious bouts of anxiety and panic and although I would try to comfort her thru it, I never truly understood it until I experienced the last six weeks. I went to the ER three times in 10 days. It started when I almost fainted at home which led to panic/chest pains. After stress test, artery CT scans, brain scans and what seems like enough blood for a family of vampires, they have concluded that my heart and arteries are perfect. Still have to follow up about the almost fainting but the anxiety/panic is still intense. I became afraid of the gym and hiking alone. In August I was hiking alone on glaciers in Iceland and now I get dizzy on elliptical as I stare at my heart rate. Monday I am going to Caribbean and anxious about flight even though I have been all over the world. Feel blindsided by this sudden appearance of anxiety.
