To my knowledge I haven't changed in the presence of my Therapist but, do look away from my doctor when describing shameful feelings or embarrassing or secretive stuff. My new T was asking me about other personalities last time I seenher and I was able to bring some of them up but, when I got to "V" I paused and had to take a deep breath and became figity and nervous. "V" is a well guarded secret that only my very best friends are aware of. V and I are very close and V doesn't come out much for personal reasons. I still need to do more reading but, if what you mean by the word "dissociate" is the same as switching then, I suppose you could say that I became my nervous and worrisome teenage self at that question. I endured a great deal of trauma as a teen and sometimes feel that I am still that person and when I'm in that frame of mind or way of thinking and percieving, I become very afraid and unconfident and worrisome. I always thought these experiences were just extreme mood swing but, according to my research it is tied in with DID but, there seem to be some here who think that I have no idea what I'm talking about and this is becoming very frustrating and triggering for me as a result. I don't know if this is just random doubt in some people or a coordinated attack to make me look like a lying jackass to the rest of the forum. Sorry for getting off topic. I'm just mixed up right now and don't know what to think.
