Generalize panic can feel overwhelming partially because you can find "no reason" for it. Maybe your feelings of paranoia are not "coupled" with the anxiety in the way you are thinking? PTSD can carry some feelings of persecution, paranoia. Did your T use the term PARANOIA? Also, please don't worry more about this. as being Paranoid and having feelings of paranoia are two different dx's, ok? I think this thread really does belong in anxiety, ok?
(((jmo))) you need to find or create a safe spot/place for you to go and feel calm. Have you done any type of meditation at all? I would also work with the T on making a really good one for you...
