Will Someone With DID be Constantly Forgetting EVERYTHING Due to Amnesia?

The person you know will likely have a fairly steady memory of daily things, but you may notice severe amnesia if they switch. Amnesia may also come up in smaller things or things that have to do with trauma – but is the person you know going to randomly completely forget who you are? Almost certainly not. Just be prepared for them to switch, for someone else in their system not to know you, and to recognize that they’re not the same.
