to my understanding, dissociating is a common trauma response. so it's possible that you dont have DID, but dissociate anyway.

all of those experiences you described (numbing out, not feeling physical pain etc) i've had too. i dont have DID, but i do have ptsd. the first 6 months of therapy with a new T i met - i dont remember any of it. i sat there and dissociated the whole time. but apparently i got through it ok, because i must have been operating at a level enough to hold conversation for an hour.

so yeah. dont need to worry about DID, i think, although it might help if you learn to manage the dissociating (so that it only happens when you want it to). i find coming into this forum useful, because it helps me manage my dissociative response (sometimes i do it even though i dont want to do it), but like i said - i dont have DID.
