Yep, definately not crazy. Maybe a little disassociation, maybe just some flight has kicked in, possibly stress, anxiety, just to name a few. You will get better as time goes on as associating each symptom to yourself, and identifying them before they get out of hand. This is just part of learning Piglet. I know what your saying, because I used to get the same sort of thing when I was still working with PTSD, and didn't know the implications of it at that stage. One minute I would be at the computer, the next I couldn't type anything, the next I had to get outside because my body told me too. It felt like I was being suffercated or something, and needed open space.

I think its part of the disassociation and reclusion that comes with PTSD, part and parcel with all other symptoms. See, when you first discovered the worst of PTSD, you probably didn't have all the symptoms, because most don't. The symptoms list is long, and I have suffered them all, so I have a good understanding of each also. Look at the symptoms of PTSD, see which one fits the best, and know what it is for the next time it strikes, so you can identify with it, then take action before it becomes too much. It is only through suffering all the symptoms, and identifying with each, that you will learn which is which, how to identify them uniquely and then put into action the techniques, skills and education you gain on each for your individual self.
