sundance, just because you're hypervigilant doesn't mean what you see isn't real... it means that you do see stuff others don't and you also put a doom and gloom meaning to what you see.

I also have such situations. (However in my case, just because I am this way doesn't mean they aren't after me ) I have been harrassed and followed (legally stalked) for eons! I had training in counter terrorism also, so I can spot things "a mile away."

There are many things to help curb how severe our reactions are, and yes, my doctors address my diet often. However, due to PTSD, it will take good, expert therapy and plenty of work work work in therapy and IRL to get to the point where you don't feel this way, nor respond this way on a daily basis, imo. TC!
