In thinking about my above post,I hope no one was offended by it. I'm not saying that those with DID don't really have alters or anything like that. I know firsthand that they are experienced as real and they really do feel like other human beings inside of us,but they're not.
Writing that out made me realize why it's so easy to think of integration as getting rid of or killing off alters.When we experience them as real humans living in us it does seem like it would be that way.The reality of it though is they are not real humans living inside of us and amandalouise's thread about integration explains DID,dissociation and integration very well.
