Just sitting here tonight & all of a sudden I got jittery & anxious and fidgety for no apparent reason. Normally I can point to something that sets me off or is making me feel off - but tonight I couldn't - it's like I just got ramped up for no reason at all. Does this happen to any of you? I mean I know anxiety is part & parcel of the whole PTSD thing but normally I can figure out what's got me on high alert and not feeling so hot...tonight I can't point to anything...which is bothersome in and of itself.
