I re read my post and it sounds harsh, which i didnt mean it to be. PTSD symptoms include flashbacks, physical reactions to thinking about the incident,avoidence, hypervigilance,increased startle response,feeling emotionally numb, feeling distant or cut off from other people, difficulty concentrating and/or sleeping, loss of interest in activities. Of course no one will have all of them, but it is common to have many of them. I think the stress that you have with your daughter would also exacerbate whatever symptoms you might have. You may well have PTSD from 9/11 and the loss that you experienced. It is also something that never goes away, 9/11, its on tv, in the papers, on the radio, constantly. You are reminded of it over and over. Going for therapy may be a good idea for you. It may help you. AS Sky said it is never cured but can be controlled. I was also affected directly by 9/11 and have ptsd from it.
