I am 48 years old. I have a lifelong panic/
anxiety disorder, have had it since my earliest memory. I too obsess specifically about health-related issues. I spent most of my young years getting obsessively x-rayed, fluor-oscopied, and otherwise examined for nothing at all. Yesterday, I had a brief moment where I thought I had found skin cancer on my body, so I had to quickly turn off that mode of thinking or I would have been looking up photos on the Internet for the next hour.
