This is part of the reason, unfortunately..I didnt want to seek help once I was told about DID, at first, when I saw the symptoms and was told it described what I was experiencing I was happy that what I was going through wasnt just me being horribly disorganized and forgetful and just plain "bad"..... and then, I realized the controversy amongst mental health professionals, I started hiding...trying to hide DID the best I can, because didnt want them doing what you're describing.

Even though I switch in T, it took a LONG time for my T to put things together..I had switched a lot in the beginning, but the alters werent making themselves known, or addressing themselves differently or trying to make it obvious....But as trust began to build, they started to completely reveal themselves, and I would have more "full switches" in therapy, because they wanted to talk...
I cant control my switches even when I dont trust someone...and Ive had people that have told me I seem different, but things can be rationalized to the DEATH.

I mean...people that know me in general just describe me as they know me, but two people might have two different views of me because they've only come in contact with certain alters....and my voice only changes sometimes, if its a "young alter" is the only time I believe it could be noticed, but usually people just ask me if Im sick or I make up excuses, like "my throat hurts today" ...if suddenly they point out a different behavior or voice tone.

I dont know but DID, isnt extremely obvious in my case....I dont have major switches constantly...but I do switch pretty much every day...I have some switches where theres no doubt I am not me, but they dont happen as often as the tiny switches..and ill suddenly find myself losing time again.
My therapist is pretty good, but it took her a very very long time to realize my switches and for my alters to make themselves known, it wasnt like one day I walked in there telling her to call me a different name... (although this may be the case with other people).

I try to hide my DID as much as possible, (usually it doesnt work very well...so I end up terminating friendships before they notice anything) only very few people know about it because I am a recluse!, but if someone spent all day following me around ...they would probably notice something eventually, but seeing someone for an hour every week...doesnt mean someone "knows" me how I am all the time.

Your therapist knows you well, and knows your case, I truly hope your therapist can validate you, have you told her yuou feel this way? I mean, after all DID is a coping mechanism its not always that obvious, its meant to help you cope with a situation that was overwhelming for you...and you could have coped a bit differently, even if its still in the context/definition of DID, but not always as obvious.

Hope things get better
