Your symptoms seem familiar to mine. I have had severe ptsd for the past 3 yrs and I get panic attaks from time to time where I feel the people who hurt me can see me even hear my thoughts and watch me and I have to get to my apartment or else I just go crazy and I feel I can't unsee others and people can feel or see me seeing them and I can't stop it. I know it is ptsd and nothing else but still very unsettling and scary.
