well.... i would say be honest with your t and tell him everything. really.
the "highway hypnosis" and "tv zoning out" are common to most everyone. but that doesn't say yes or no.
I used to tell "stories" to my youth paster to tell her things about me... I don't know that that is odd or special to any dx. I hadn't even thought about it until you mentioned it.
but feeling like different ppl inside and doing things that are not "characteristic" of you - it could be... and it could not be too.
If you are DID - it is not the end of the world. There are different levels of it and ways to get through. The important thing is learning about yourself.
Of 3 therapists, one said no i am not DID, one said i am DID/MPD, and one won't tell me because "I do not see ppl as dx's, but more as processes."
but the more i learn about myself, my behaviors, my actions, my thoughts... the more power i have to make changes if i want to, and to know the reasoning behind them.
Does that make sense?
