Eagle, PTSD is quite a wild beast to put it mildly. The obsessions you have in regard to stockpiling in case of another terrorist attack, is part of the OCD component that comes with PTSD. Some doctors try and tell you that you have OCD, but in fact with PTSD you will actually get some OCD qualities. Let me ask you this. If another terrorist attack occurred, what is your stockpile of items going to do for you? A terrorist attack on a part of a country, doesn't stop the country, nor does it often even stop the part that was attacked. Look at the London underground! Within days it was cleaned up, and whilst it happened, London didn't stop functioning. Even 9/11, the city still functioned, food was still available, water, clothing, showers, etc etc...

Now then you could say, New Orleans! If you lived in something like that, all the stockpiles in the world wouldn't off helped you, because they would have all been under water and washed away. Obsessive Compulsive Behaviour (OCD) has to be reasoned. PTSD is what causes it from fear, and when that fear is reasoned with, OCD is no longer present.

Just like your nightmares. People think that nightmares have to be about or resemble their trauma, but in fact they can have nothing too do with any off your past at all, but based more upon the fears that your mind is creating daily based on your past. If you never feared snakes for instance, but your trauma was never dealt with, then you could suddenly become to fear them, which means you could then have nightmares about snakes. Your mind is fed by fear... the fear is caused by the trauma, the trauma causes PTSD. To reason, understand and accept trauma, removes the fear, which in turn removes the nightmares.

So no, your not crazy, your not losing the plot, you just have uncontrolled PTSD. When your ready to deal with your trauma, then as you do so, the side effects of PTSD become less and less during the course off it.
