There is so much misunderstanding about what DID needs to look like, what needs to be present or absent for someone to have DID, I think a thread might be useful where some of us list reasons we have thought we didn't have DID. Or maybe reasons you see in others' posts that assume a particular piece of evidence, like a certain type of alter or behavior, is needed to have DID. Or reasons that keep coming up for you, even though you generally know you have DID.
For me:
I must not have DID because...I don't lose time.
In fact, we don't think we have in adulthood, just snippets and even that has been rare. I lost all sorts of time in childhood but had no memory until recent years that that happened. Aaagh, stupid past versions of the DSM! If only they had mentioned that losing time was not required in the present to have DID, I would have pursued whether I was multiple or not decades ago. Or if they had mentioned that you can have amnesia about your amnesia.
