I have experienced what you're talking about. I was abused as a child & I had a subsequent split...in fact when I took the myers-briggs test I came out as a T but nowadays I am a borderline T/F.
Anyhow back to the posting! I didn't have therapy to help me out of it & actually the state was so pervasive I didn't even notice that I didn't "feel" the way others did. I didn't cry & considered that a positive. It wasn't until I moved away from the source of the intense trauma (my parents) that I started to wake back up.
& then after that I had to confront the intense emotions underneath & begin to heal what was going on with me. That process took years but now I am a fully emotional person
Anyways, I wonder what the article contained which triggered such intense panic as you described? I would ask your deepest self that question: What was triggered by the article? What in the article resonated so deeply that I panicked?
Try taking a big breath & stepping back. Any insight you have inside will be more helpful for you than any guesses the rest of us may have. I do hope I have been of some help through my own experience.
