NO! When alters integrate no one goes away... but the whole is comprised of everyone, as it once was...is again... different, yes, but like everyone is when they grow older.

Some parts of you might change roles on the way to integration (if that is what your system chooses to do, some ppl with DID choose not to integrate.) While someone might have a part that fights physically... that part might become the one who raises red flags for ppl the system doesn't like (rather than fight.) That kind of change would be good, right?

But no one has to disappear, no one "dies", and no one has to worry that they are "just" an alter, imo. Each part of a person is important! TC
