my thoughts... like the disclaimer at the bottom of the page states you will need to contact your own treatment providers. the questions you are asking...

title question

is this depersonalization, dissociation or...?

only your own treatment providers can answer that based on your own individual symptoms, problems, life, medications, other accompanying symptoms your own physical and mental health and other factors that we on line are not privy to.

questions in post....

does this make sense... again we cant say whether this makes sense or not for you and your own health. for me what I can say is that yes your post made sense to me, good sentence structure, good vocab, I have had some of the same problems but in me they were called many different things by my own treatment providers based on my own individual things like my own meds, my own life, my own health issues, my own mental health issues, my cultural background, my religion.....

for example you mention difficulty being in your body. for me that's part of my bipolar with psychosis symptoms. its also part of my medications and its also part of my native America culture. my spiritual beliefs and practices also took that out of the running for being part of my dissociative disorders for having visions / OBE (out of body experiences) happens with religions native American cultures and others too and can also happen with medications / meditation and other common practices. the kind that fits dissociative disorders is vastly different than just my having difficulty staying in my body.

what did make it fit in was that the problem was trauma trigger related and the fix for my dissociative disconnection from my body was called grounding, relaxation and locating the trigger. fixing things in my life so that I was no longer triggered by what ever was causing the problem. these things took addressing and working with my mental health treatment providers

again we can not tell you what something is with in your body and whether something makes sense for you. for that you will need to contact your treatment providers. psych central cant do that for you. here all we do is the same thing as if you were sitting somewhere chatting with your friends. sharing your life and situations with your friends.
