AYC, yes I was. Thankfully I no longer experience any (severe) symptoms of PTSD. But, it was very rough going for a few months. Even worse was not knowing, realizing, or acknowledging what was happening to me. It was very frightening. One of the most striking things was that when I came to terms with what was happening I wanted to hide it from anyone else, family included. I actually now understand people with mental illness becoming shut-ins and stewing in their own misery and exacerbating their disease. You feel that if it gets out you will be looked down upon. Pitied. Look, the nebach. Having experienced it myself now, (and BTW, it manifested itself many months after 9/11) I think I have a newfound understanding and patience with those that may suffer from mental illness. Kudos to mental health professionals. You do great work.
